Introduction
The Timestamp Converter maps Unix epoch values (seconds or milliseconds) to readable dates and back—essential when logs, JWT exp claims, and databases use epoch time while you reason in local clocks. Confirm whether your source uses seconds or milliseconds; mixing units is a common bug. Use timezone tools when you need to shift regions, not only to decode epoch. During incidents, convert timestamps immediately to align events with deploys, cron windows, or user reports. Cross-check around daylight saving changes when timelines look off.

How to use
- Paste a Unix timestamp (seconds or milliseconds—match the UI mode).
- Or pick a calendar date/time to convert to epoch.
- Verify the timezone interpretation matches your source system.
- Copy the converted value into your query, ticket, or script.
- Cross-check with another sample if the incident spans DST changes.
Use cases
- Translate log timestamps into local incident timelines
- Convert JWT exp values to confirm expiry windows
- Build queries against time-series databases
- Communicate timelines across teams in different regions
- Verify scheduled jobs and cron windows against epoch values
FAQ
- Seconds or milliseconds?
- Confirm which unit your logs use. Millisecond timestamps are larger and often 13 digits.
- Does this replace timezone conversion?
- Use the Timestamp Converter for epoch mapping; use Timezone Converter when shifting zones.
- Why does my timestamp look wrong?
- Check DST boundaries, timezone defaults, and unit mistakes.
- Can I use this for JWT exp?
- Yes—decode exp to a human time to compare with your clock.
- Is the tool free?
- Yes. DevToolDock provides this timestamp utility for free.
