What Does Epoch 0 Mean?
Epoch 0 is the origin of Unix time. All Unix timestamps are measured as the number of seconds before or after this exact moment: midnight on January 1, 1970, Coordinated Universal Time (UTC). In ISO 8601 format, this is 1970-01-01T00:00:00Z.
The Unix epoch was chosen by the creators of Unix at Bell Labs. It was a round, recent date at the time Unix was being developed in the late 1960s. Today, virtually every computer system uses this same reference point for time.
