How it works
Unix time counts seconds since 1 January 1970 UTC.
Examples
- Epoch 1794321000
UTC: 2026-11-10 14:30:00 ISO 8601: 2026-11-10T14:30:00.000Z Read as: seconds
- Milliseconds 1794321000000
UTC: 2026-11-10 14:30:00 ISO 8601: 2026-11-10T14:30:00.000Z Read as: milliseconds
- A date to epoch
Epoch seconds: 1794321000 Epoch milliseconds: 1794321000000 ISO 8601: 2026-11-10T14:30:00.000Z
Limitations and assumptions
Values with 13 digits are read as milliseconds, shorter as seconds.
