Epoch Buddy: Unix Timestamp & Date Converter

Tracking since Apr 1, 2026.

Changelog

• May 10, 2026
  description

  Stop copying epoch timestamps to random websites. Epoch Buddy converts Unix
  timestamps to human-readable dates instantly — right on any webpage or from the
  popup. Seconds, milliseconds, dates, relative time — all covered. Fast and
  private: all conversions happen locally; your inputs and results never leave
  your browser.
  
  
  WHY DEVELOPERS LOVE EPOCH BUDDY
  
  Epoch timestamps are everywhere: server logs, monitoring dashboards, API
  responses, database records, incident timelines, support tickets, and more.
  Every time you see a 10-digit or 13-digit number and wonder "what time was
  that?", Epoch Buddy gives you the answer in seconds — without leaving your tab
  and without any external site.
  
  
  FEATURES
  
  1) Highlight-to-Convert on Any Webpage
  Select any epoch timestamp on any website and get an instant inline popup showing:
    - Epoch in seconds and milliseconds
    - One row per timezone you have configured (Local, UTC, or any IANA zone you
      pick in Settings — e.g. Asia/Kolkata, America/Los_Angeles)
    - Each row includes the UTC offset and full timestamp
    - Relative time (e.g. "3 hours ago" or "in 2 days")
    - One-click copy buttons for each value
  Long timezone labels wrap cleanly without breaking layout. Works on regular
  text, input fields, and text areas across every website.
  
  2) Popup Converter with Three Powerful Modes
  Click the extension icon to open a clean, keyboard-friendly popup with three tabs.
  Your current timezone and UTC offset are shown in the header at a glance.
  
    A) Epoch to Date
    Paste or type any Unix epoch value (seconds or milliseconds). The input
    auto-fills with the current epoch and live-refreshes every second. Pause it
    by clicking in — it resumes when you clear the field. A dedicated clock
    button copies the current millisecond timestamp and fills the input field.
    Output: Epoch (s), Epoch (ms), one row per configured timezone with its UTC
    offset, and Relative time.
  
    B) Date to Epoch
    Enter a date and time using validated numeric fields (year, month, day, hour,
    minute, second, millisecond) with per-field error highlighting. Pick any of
    your configured timezones from the dropdown — not just Local and UTC. Time
    presets — Start of Day, End of Day, or Current Time — sit inline with the
    time fields for quick access.
    Click "Convert ISO String" to flip the form into ISO 8601 mode: paste an ISO
    string (e.g. 2026-03-19T12:00:00.000Z) and, when the string has no offset,
    pick any of your configured zones as the fallback. Click "Enter Date
    Manually" to flip back.
    Output: Epoch (ms), Epoch (s), Relative time.
  
    C) Relative to Epoch
    Build a timestamp relative to "now". Choose Ago or From Now, then enter any
    combination of Days, Hours, Minutes, Seconds, and Milliseconds. Overflow
    values are automatically normalized (e.g. 90 minutes becomes 1h 30m). Smart
    display shows only relevant units — no clutter.
    Output: Epoch (s), Epoch (ms), one row per configured timezone, and Relative
    time.
  
  3) Conversion History
  Your last 10 conversions are saved locally with quick copy buttons. Each entry
  expands to show per-timezone rows for every zone you have configured. View them
  anytime in the History section. Clear all history with one click. Nothing is
  sent to any server — everything stays in your browser.
  
  4) Timezone Settings
  Open the gear icon in the header to manage your timezones. Add any IANA zone
  (e.g. Europe/London, Asia/Tokyo, America/New_York), remove ones you do not
  need, and drag-and-drop to reorder them. Your configured list drives every
  output surface: the on-page popup, all three converter tabs, the history
  entries, and the ISO fallback-timezone dropdown — so your preferred zones
  always show up in your preferred order.
  
  5) Dark Mode
  Full dark mode support that follows your system preference, or set it manually
  to Light, Dark, or System. The same polished, segmented theme picker is
  available both in the header menu and in the Settings page. Applied across the
  popup and the on-page conversion tooltip.
  
  6) One-Click Copy
  Every converted value comes with a copy button. Hover over any result row in the
  on-page popup or click the copy icon in the extension popup. Copies to clipboard
  instantly.
  
  
  PRIVACY & PERFORMANCE
  
  - All conversions run locally — no conversion inputs or results are sent anywhere
  - Works fully offline: the converter itself never needs the network
  - No accounts, no sign-ups, no logins
  - Anonymous usage analytics (event counts only — no page content, no personal
    data, no conversion values) help us understand which features are used. You
    can disable analytics any time from the Settings screen. Details in the
    privacy policy.
  - Lightweight and blazing fast
  - Open source: https://github.com/ShivamS136/epoch-buddy
  
  
  SUPPORTED INPUTS
  
  - Unix epoch in seconds (10 digits, e.g. 1714000000)
  - Unix epoch in milliseconds (13 digits, e.g. 1714000000000)
  - Commas and underscores allowed (e.g. 1,714,000,000 or 1_714_000_000)
  - ISO 8601 strings (e.g. 2026-03-19T12:00:00.000Z) in Date → Epoch ISO mode
  
  
  PERFECT FOR
  
  - Backend & frontend developers debugging timestamps
  - DevOps & SRE teams during incident response
  - Log analysis in observability and monitoring tools

  - Anyone tired of Googling "epoch to date converter"
  
  
  WHAT'S NEW IN v1.7.0
  
  - New Settings → Analytics toggle: opt out of anonymous usage counts at
    any time. Only event names (like "epoch_to_date", "settings_opened")
    and a random install ID are ever sent — never your conversion values,
    the text you selected on a page, or any page content. See the privacy
    policy for the full list.
  - First-time notice for existing users explains the anonymous analytics
    and how to disable it in one click.
  
  WHAT'S NEW IN v1.6.0
  
  - Settings page accessible from the header gear icon
  - Add any IANA timezone to your list (Europe/London, Asia/Tokyo, and hundreds
    more), remove ones you do not need, and drag-and-drop to reorder
  - Converter results, the on-page popup, and history entries all now show one
    row per configured timezone — no more being locked to Local and UTC
  - ISO-string fallback timezone picker now uses your configured zones, so you
    can resolve offset-less ISO strings against any zone you use
  - Theme picker in Settings matches the polished header menu (segmented
    control with Light / Dark / System icons)
  - Long timezone labels wrap gracefully in both the on-page popup and the
    extension popup — no more layout distortion for names like
    "America/Argentina/Buenos_Aires"
  
  WHAT'S NEW IN v1.5.0
  
  - Popup feedback footer with a 5-star rating: tap “Rate Extension” / “Rate Add-on” to show stars,
    then choose a rating. Ratings 1–3 can open a pre-filled Google Form; 4–5 can open this browser’s
    store review page.
  - “Hide the footer” after you rate; stored only on your device until you reinstall the extension.
  
  WHAT'S NEW IN v1.4
  
  - ISO 8601 string input mode in Date → Epoch (with fallback timezone selector)
  - Copy current epoch (ms) button in Epoch → Date that also fills the input field
  - Numeric input fields with per-field validation and error highlighting
  - Automatic normalization of overflow values in Relative tab
  - Time presets moved inline with time fields for a more compact layout
  - Current timezone and UTC offset shown in the popup header
  - Date fields require a value; time fields default to zero on blur
  
  WHAT'S NEW IN v1.3
  
  - Relative to Epoch converter tab
  - Time presets (Start of Day, End of Day, Now)
  - Dark mode with system preference detection
  - Improved on-page popup positioning with smart arrows

  - DevOps & SRE teams during incident response
  - Log analysis in observability and monitoring tools
  - API development and testing
  - QA engineers validating timestamp fields
  - Database administrators inspecting epoch columns
  - Anyone tired of Googling "epoch to date converter"
  
  
  WHAT'S NEW IN v1.7.0
  
  - New Settings → Analytics toggle: opt out of anonymous usage counts at
    any time. Only event names (like "epoch_to_date", "settings_opened")
    and a random install ID are ever sent — never your conversion values,
    the text you selected on a page, or any page content. See the privacy
    policy for the full list.
  - First-time notice for existing users explains the anonymous analytics
    and how to disable it in one click.
  
  WHAT'S NEW IN v1.6.0
  
  - Settings page accessible from the header gear icon
  - Add any IANA timezone to your list (Europe/London, Asia/Tokyo, and hundreds
    more), remove ones you do not need, and drag-and-drop to reorder
  - Converter results, the on-page popup, and history entries all now show one
    row per configured timezone — no more being locked to Local and UTC
  - ISO-string fallback timezone picker now uses your configured zones, so you
    can resolve offset-less ISO strings against any zone you use
  - Theme picker in Settings matches the polished header menu (segmented
    control with Light / Dark / System icons)
  - Long timezone labels wrap gracefully in both the on-page popup and the
    extension popup — no more layout distortion for names like
    "America/Argentina/Buenos_Aires"
  
  WHAT'S NEW IN v1.5.0
  
  - Popup feedback footer with a 5-star rating: tap “Rate Extension” / “Rate Add-on” to show stars,
    then choose a rating. Ratings 1–3 can open a pre-filled Google Form; 4–5 can open this browser’s
    store review page.
  - “Hide the footer” after you rate; stored only on your device until you reinstall the extension.
  
  WHAT'S NEW IN v1.4
  
  - ISO 8601 string input mode in Date → Epoch (with fallback timezone selector)
  - Copy current epoch (ms) button in Epoch → Date that also fills the input field
  - Numeric input fields with per-field validation and error highlighting
  - Automatic normalization of overflow values in Relative tab
  - Time presets moved inline with time fields for a more compact layout
  - Current timezone and UTC offset shown in the popup header
  - Date fields require a value; time fields default to zero on blur
  
  WHAT'S NEW IN v1.3
  
  - Relative to Epoch converter tab
  - Time presets (Start of Day, End of Day, Now)
  - Dark mode with system preference detection
  - Improved on-page popup positioning with smart arrows
  - Conversion history with quick copy

  Stop copying epoch timestamps to random websites. Epoch Buddy converts Unix
  timestamps to human-readable dates instantly — right on any webpage or from the
  popup. Seconds, milliseconds, dates, relative time — all covered. Fast, private,
  and works completely offline.
  
  
  WHY DEVELOPERS LOVE EPOCH BUDDY
  
  Epoch timestamps are everywhere: server logs, monitoring dashboards, API
  responses, database records, incident timelines, support tickets, and more.
  Every time you see a 10-digit or 13-digit number and wonder "what time was
  that?", Epoch Buddy gives you the answer in seconds — without leaving your tab,
  without any external site, and without ever sending your data anywhere.
  
  
  FEATURES
  
  1) Highlight-to-Convert on Any Webpage
  Select any epoch timestamp on any website and get an instant inline popup showing:
    - GMT / UTC time
    - Local time in your timezone
    - Relative time (e.g. "3 hours ago" or "in 2 days")
    - One-click copy buttons for each value
  Works on regular text, input fields, and text areas across every website.
  
  2) Popup Converter with Three Powerful Modes
  Click the extension icon to open a clean, keyboard-friendly popup with three tabs.
  Your current timezone and UTC offset are shown in the header at a glance.
  
    A) Epoch to Date
    Paste or type any Unix epoch value (seconds or milliseconds). The input
    auto-fills with the current epoch and live-refreshes every second. Pause it
    by clicking in — it resumes when you clear the field. A dedicated clock
    button copies the current millisecond timestamp and fills the input field.
    Output: Epoch (ms), GMT/UTC, Local time, Relative time.
  
    B) Date to Epoch
    Enter a date and time using validated numeric fields (year, month, day, hour,
    minute, second, millisecond) with per-field error highlighting. Switch between
    Local and GMT/UTC timezone. Time presets — Start of Day, End of Day, or
    Current Time — sit inline with the time fields for quick access.
    Click "Convert ISO String" to flip the form into ISO 8601 mode: paste an ISO
    string (e.g. 2026-03-19T12:00:00.000Z) with an optional fallback timezone
    selector, then convert. Click "Enter Date Manually" to flip back.
    Output: Epoch (ms), Epoch (s), Relative time.
  
    C) Relative to Epoch
    Build a timestamp relative to "now". Choose Ago or From Now, then enter any
    combination of Days, Hours, Minutes, Seconds, and Milliseconds. Overflow
    values are automatically normalized (e.g. 90 minutes becomes 1h 30m). Smart
    display shows only relevant units — no clutter.
    Output: Epoch (ms), UTC/UTC, Local time, Relative time.
  
  3) Conversion History
  Your last 10 conversions are saved locally with quick copy buttons. View them
  anytime in the History section. Clear all history with one click. Nothing is
  sent to any server — everything stays in your browser.
  
  4) Dark Mode
  Full dark mode support that follows your system preference, or set it manually
  to Light, Dark, or System. Applied across both the popup and the on-page
  conversion tooltip.
  
  5) One-Click Copy
  Every converted value comes with a copy button. Hover over any result row in the
  on-page popup or click the copy icon in the extension popup. Copies to clipboard
  instantly.
  
  
  PRIVACY & PERFORMANCE
  
  - Zero external network requests — works 100% offline
  - No accounts, no sign-ups, no logins
  - No analytics, no trackers, no telemetry
  - No data leaves your browser — ever
  - Lightweight and blazing fast
  - Open source: https://github.com/ShivamS136/epoch-buddy
  
  
  SUPPORTED INPUTS

  - Unix epoch in milliseconds (13 digits, e.g. 1714000000000)
  - Commas and underscores allowed (e.g. 1,714,000,000 or 1_714_000_000)
  - ISO 8601 strings (e.g. 2026-03-19T12:00:00.000Z) in Date → Epoch ISO mode
