  • time function in cpan Time::HiRes module.

What is the Current Epoch(Unix) time in Perl

Epoch time is the total number of seconds, the ie long number represents that already passed from 1 January 1970 UTC.

the total number of seconds per day is 24\* 60\*60 seconds. Epoch time returns the long number between the current time and 1 January 1970.

It is also called Epoch Unix time.

Perl language provides API for getting Unix time. There are cpan modules that also provide a Date API for manipulation of Epoch Time.
the base year is 1970 since UNIX OS was introduced at that time.

EPOCH time = unix epoch time = Number of millseconds 01/01/1970 00:00:00

Perl Unix timestamp in milliseconds

Perl provides a native time() function that returns the current epoch Unix time. ``perl my $unixTime = time(); print “$unixTime”;

Output:
```markdown
1671371398

Another way using the time function in the Time::HiRes module

use strict;
use warnings;
use Time::HiRes qw(time);

my $unixTime = time();
print "$unixTime";
1671371399.287

How to Convert timestamp to Date and time in Perl

First, get timestamp using the time() function next, pass the timestamp to the localtime() function which returns the datetime object.

Here is an example

use strict;
use warnings;
use Time::HiRes qw(time);

my $unixTime = time();
print "Timestamp: $unixTime\n";

my $date = localtime($unixTime );
print "Convert timestamp to date: $date";

Output:

Timestamp: 1671377748.28593
