Date and time
Epoch Time Converter for API Logs
API logs often store events as epoch timestamps because they are compact and timezone-neutral. The hard part is quickly turning those numbers into readable dates during debugging.

A 10-digit value is usually Unix seconds. A 13-digit value is usually milliseconds. Getting this wrong can make a log event appear years away from the real time.
Compare event order
After conversion, check whether login, request, webhook, and error events happened in the expected order. This helps isolate race conditions and delayed jobs.
Use UTC for backend discussions
When sharing timestamps with developers or support teams in different locations, UTC avoids timezone confusion.
FAQ
Why do logs use epoch time?
Epoch time is compact, numeric, and easy for systems to sort or compare.
Should I convert logs to local time or UTC?
Use UTC for technical debugging and local time for human scheduling context.
What if the converted date looks wrong?
Check whether the original value was seconds or milliseconds.
