Good to know
Unix time counts from 1 January 1970, 00:00:00 UTC. All date input and output here use UTC, regardless of your device timezone. The Z suffix means UTC. Negative timestamps represent dates before 1970. When converting to seconds, fractional seconds round down.
Example: 1704067200 seconds and 1704067200000 milliseconds both represent 1 January 2024, 00:00:00 UTC.
