I agree with graff about using a Date:: module. How would you create the end given this start?
script.pl --start 'Dec 31 23:59'
Consider the following:
use Date::Calc qw/Localtime/;
my $startDateTime = 'Dec 31 23:59:';
my $addMinutes = 2;
my $year = ( Localtime(time) );
$startDateTime .= '00 ' . $year;
my $startSeconds = str2time($startDateTime);
my $endSeconds = $startSeconds + $addMinutes * 60;
print "\$startSeconds: $startSeconds; \$endSeconds: $endSeconds; Delta
. ( $endSeconds - $startSeconds );
$startSeconds: 1357027140; $endSeconds: 1357027260; Delta: 120
You can use Date::Parse to convert a line's date/time string to seconds, and then print the line if the value's within the $startSeconds and $endSeconds range.
