About this extension
Epoch Buddy turns Unix epoch timestamps into readable dates instantly — from any
page selection or from the popup. Fast, private, and works offline.

WHY EPOCH BUDDY?

Epoch values show up everywhere: logs, dashboards, monitoring tools, API
responses, incident timelines, tickets, and docs. Epoch Buddy helps you
translate those numbers into human time in seconds—without leaving the tab.

KEY FEATURES

1) Highlight-to-Convert on Any Webpage
- Select an epoch value (10-digit seconds or 13-digit milliseconds)
- Get a small popover near your selection with:
- GMT/UTC time
- Local time
- Relative time (ago / from now)
- One-click copy buttons (appear on hover)

2) Popup Converter (Tabbed)
A clean, keyboard-friendly popup with three modes:

A) Epoch → Date
- Auto-fills current epoch (seconds) and refreshes every second
- Refresh pauses while you focus/edit, resumes when cleared/blurred
- Output includes:
- Epoch (ms)

- Local time
- Relative time

B) Date → Epoch
- Enter date + time fields (keyboard input)
- Choose Local or GMT/UTC
- Output includes:
- Epoch (ms)
- Epoch (s)

C) Relative → Epoch

- Inputs:
- Ago / From Now
- Days, Hours, Minutes, Seconds, Milliseconds
- Output includes:
- Epoch (ms)
