💡 Pro Tips & Best Practices
✓
Unix timestamps in seconds are 10 digits long; in milliseconds they are 13 digits long.
✓
JavaScript uses milliseconds by default — always check which unit an API expects.
✓
Store dates as Unix timestamps in databases for timezone-agnostic, sortable date storage.
✓
The Unix epoch date is January 1, 1970 00:00:00 UTC — timestamp 0.
✓
Negative timestamps represent dates before 1970 — some systems do not handle these.
✓
For API integrations, always clarify whether a timestamp field expects seconds or milliseconds.
✓
Use ISO 8601 format (2025-01-01T00:00:00Z) for human-readable dates in APIs alongside timestamps.
