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 strict; use warnings; use Date::Parse; use Date::Calc qw/Localtime/; my $startDateTime = 'Dec 31 23:59:'; my $addMinutes = 2; my $year = ( Localtime(time) )[0]; $startDateTime .= '00 ' . $year; my $startSeconds = str2time($startDateTime); my $endSeconds = $startSeconds + $addMinutes * 60; print "\$startSeconds: $startSeconds; \$endSeconds: $endSeconds; Delta +: " . ( $endSeconds - $startSeconds );

Output:

$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.

[ambrus]: 1nickt: for some reason, these days they call every computer "gaming", even ones that gamers wouldn't buy. I've bought a keyboard that was labelled "gamer", despite that it has hard springs and seems to be way better for typing than for gaming;
[1nickt]: I though the gamers like that because they bash the keys so hard.
[ambrus]: and I've seen motherboards with no fast expansion ports for a video card but built-in hardware RAID advertized as "gaming".

[ambrus]: 1nickt: my impression is that the gamers like the softer springs, because fast reaction time is more important to them then feedback from keypresses to recognize typos.
[1nickt]: Ah, I see. I did read some gamer mag reviews, and yes, they lamented the fact that laptops with no discrete video card are sold as "gaming" hardware.
[1nickt]: But, they do have red keyboard backlighting! And gargoyles on the front, or words like "Maxxx" here and there. They know their demographic!
[1nickt]: True gamers don;t buy Dells, HPs, or Lenovos, I think ;-)
[ambrus]: The keyboard I bought doesn't have backlighting. I specifically had to select for that, because so many keyboards these days have lights. Why would I want lights in the keyboard? I want lights in the room, such as on the ceiling, not in the keyboard.
