Epoch Buddy: Unix Timestamp & Date Converter de Shivam Sharma

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, Jira tickets, Datadog, Grafana,
Kibana, Splunk, 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:

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.
Output: Epoch (ms), GMT/UTC, Local time, Relative time.

B) Date to Epoch
Enter a date and time using intuitive fields (year, month, day, hour, minute,
second, millisecond). Switch between Local and GMT/UTC timezone. Use quick
presets — Start of Day, End of Day, or Current Time — to fill time fields
instantly.
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. Smart display
shows only relevant units — no clutter.
Output: Epoch (ms), GMT/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.
