Unix time counts seconds since 1 January 1970 UTC, ignoring leap seconds. 1767225600 is 1 January 2026 at 00:00 UTC, which is 20454 days after the epoch and a Thursday. JavaScript works in milliseconds and some databases in microseconds, which is why the unit must be stated.
Unix time
seconds elapsed since 1970-01-01T00:00:00Z
Unit scaling
milliseconds = seconds x 1000; microseconds = seconds x 1,000,000
A signed 32-bit timestamp overflows on 19 January 2038. Modern systems use 64-bit values, which last for 292 billion years.
No. It pretends every day has exactly 86,400 seconds, which is why it drifts from true atomic elapsed time by the accumulated leap seconds.
