Frequently Asked Questions (FAQ)
Unix time (also known as POSIX or Epoch time) is a system for tracking time expressed as the total number of elapsed seconds since 00:00:00 UTC on 1 January 1970 (excluding leap seconds).
Systems using a 32-bit signed integer to store Unix timestamps will overflow on January 19, 2038 at 03:14:07 UTC (reaching 2,147,483,647 seconds). Modern 64-bit systems resolve this limitation entirely, extending epoch capacity for billions of years.
