Unix Timestamp Explained
The Unix timestamp is a deceptively simple idea that underpins most date handling in software. Here is what it actually represents.
Seconds since the epoch
A Unix timestamp is the number of seconds since midnight UTC on 1 January 1970 — the "epoch". Because it is a single integer, it is easy to store, compare and sort.
Units and the 2038 problem
Timestamps appear in seconds or milliseconds depending on the system. Older 32-bit signed counters overflow in January 2038, which is why modern systems use 64-bit values.
