What Is Epoch Time?

Unix epoch time is the number of seconds (or milliseconds) since 1970-01-01 00:00:00 UTC. It is widely used in logs, APIs, databases, and analytics systems.

Common Mistake To Avoid

The most frequent bug is mixing seconds and milliseconds.
Example: 1715942400 (seconds) vs 1715942400000 (milliseconds).

Where This Is Useful

  • Reading timestamps from server logs.
  • Debugging time-related API payloads.
  • Converting user-facing dates into backend-friendly values.
