TheUnix TimestamporUnix Epoch TimeorPOSIX Timeis a technique to indicate about a point in time. It can be a number of seconds between particular date time and that have passed since1 January 1970at Coordinated Universal Time(UTC). So theEpochis Unix time 0 (1-1-1970) but it is also ...
In Unix and Linux, dates are represented internally as the number of seconds since January 1, 1970 at 00:00 GMT. But you can convert it into a normal date.
The unix time stamp is a way to track time as a running total of seconds. This count starts at the Unix Epoch on January 1st, 1970 at UTC. Therefore, the unix time stamp is merely the number of seconds between a particular date and the Unix Epoch. It should also be pointed out (th...
