Epoch - The creation of the world
In case you were wondering what is the epoch that sometime we talk about, it is the "start of the time" - as understood by your Linux/Unix-based computer.
Also know as the "creation of the world".
As you will see, it happened to fall on a Thursday.
use strict; use warnings; use 5.010; use DateTime; say scalar gmtime(0); say scalar localtime(0); my $dt = DateTime->from_epoch( epoch => 0 ); say $dt; my $time = time(); say $time; say scalar localtime($time);
In the output first you'll see the epoch in London (or more precisely in Greenwich) then the same in any location that is in the GMT+2 timezone.
Then the same, formatted using the DateTime class.
Finally the value returned by the time function which is the current time in seconds since the epoch and the same in a more readable format. (Yes, you see it well, I wrote this article on a Sunday at 7 am.)
