Although it is not a well known fact, all awk releases are able to retrieve the current epoch time by standard :
Code:
$ awk 'BEGIN {srand();time=srand();print time}'

DateTime::Format::Epoch::DotNet(3pm)			User Contributed Perl Documentation		      DateTime::Format::Epoch::DotNet(3pm)

NAME
DateTime::Format::Epoch::DotNet - Convert DateTimes to/from .NET epoch seconds SYNOPSIS
use DateTime::Format::Epoch::DotNet; my $dt = DateTime::Format::Epoch::DotNet->parse_datetime( 1051488000 ); DateTime::Format::Epoch::DotNet->format_datetime($dt); # 1051488000 my $formatter = DateTime::Format::Epoch::DotNet->new(); my $dt2 = $formatter->parse_datetime( 1051488000 ); $formatter->format_datetime($dt2); DESCRIPTION
This module can convert a DateTime object (or any object that can be converted to a DateTime object) to the number of seconds since the epoch defined in the .NET Framework SDK. Note that this epoch is defined in the local time zone. This means that these two pieces of code will print the same number of seconds, even though they represent two datetimes 6 hours apart: $dt = DateTime->new( year => 2003, month => 5, day => 2, time_zone => 'Europe/Amsterdam' ); print $formatter->format_datetime($dt); $dt = DateTime->new( year => 2003, month => 5, day => 2, time_zone => 'America/Chicago' ); print $formatter->format_datetime($dt); METHODS
Most of the methods are the same as those in DateTime::Format::Epoch. The only difference is the constructor. o new() Constructor of the formatter/parser object. It has no parameters. SUPPORT
Support for this module is provided via the datetime@perl.org email list. See http://lists.perl.org/ for more details. AUTHOR
