What is Epoch?

The Epoch time is the current time measured in the number of seconds since the Unix Epoch. Epoch 0 is January 1, 1970, 00:00:00 GMT (ISO 8601: 1970-01-01T00:00:00Z). Leap seconds are not used in Unix time.

Normal Time	Seconds
1 minute	60 seconds
1 hour	3600 seconds
1 day	86400 seconds
1 week	604800 seconds
1 month (30.44 days)	2629743 seconds
1 year (365.24 days)	31556926 seconds

Programming with Epoch

The Unix Epoch time can be retrieved in various programming languages using built-in functions. Below is a reference for obtaining the current Unix timestamp in different environments.
