Developer Documentation & Guidance

Practical developer scenarios, best practices, and common mistakes to avoid.

When Should I Use This Tool?

•Converting Unix epoch timestamps (seconds or milliseconds) to human-readable ISO/UTC dates.
•Generating epoch timestamps for database records, audit logs, or token expiration claims.
•Debugging timezone offsets and UTC date string conversions.

Developer Best Practices

✓Store and transmit timestamps in UTC or Unix epoch format across all system boundaries.
✓Distinguish clearly between 10-digit (seconds) and 13-digit (milliseconds) epoch values.
✓Format dates for display using standard ISO 8601 strings (YYYY-MM-DDTHH:mm:ssZ).

Common Developer Mistakes

!Confusing Unix seconds (10 digits) with milliseconds (13 digits).
!Assuming local server timezone applies to global users or remote database instances.
!Parsing non-standard date strings without specifying explicit timezone offsets.
