Seconds conversion

dda has asked for the wisdom of the Perl Monks concerning the following question:

Hello All, I need to convert a value, given in seconds, to string like "1 day, 10 hours, 23 min, 44 sec". I wrote a simple script, but I'd like to check if there is any standard (?) ways to do it, or, at least, more elegant. Or, probably, the code has some bugs?

Code:

use strict;

my $idle = 1332443;
my ($days, $hours, $min, $sec);
$days = round($idle/86400);
$idle -= $days*86400;
$hours = round($idle/3600);
$idle -= $hours*3600;
$min = round($idle/60);
$idle -= $min*60;
$sec = $idle;

print "$days days, $hours hours, $min min, $sec sec\n";

sub round {
    my $value = $_[0];
    return (sprintf('%.0f', 2 * $value / 2));
}

Thanks.

Time::Duration is nice for this: `>perl -MTime::Duration -e "print duration_exact(1332443)" 15 days, 10 hours, 7 minutes, and 23 seconds` [download] But even nicer in that it will supress the least significant units for larger durations: `>perl -MTime::Duration -e "print duration(1332443)" 15 days and 10 hours` [download] If you'd rather do it yourself, you could avoid all the sprintfs with something like: `my $d = int( $seconds / 86400 ); my $h = int( ($seconds - $d86400) / 3600 ); my $m = int( ($seconds - $d86400 - $h*3600) / 60 ); my $s = $seconds % 60; print "$d days, $h hours, $m min, $s sec\n";` [download] and if you want to be neat you can always fix the pluralization with a few bits like `my $day_string = $d > 1 ? 'days' : 'day';` -- I'd like to be able to assign to an luser	[reply] [d/l] [select]

I am not sure about a standard, but this idea may work: #!/usr/bin/perl use strict; print "${\SecondsToTime(22)}\n"; print "${\SecondsToTime(220)}\n"; print "${\SecondsToTime(2200)}\n"; print "${\SecondsToTime(22000)}\n"; exit; sub SecondsToTime { # Takes a number of seconds, and creates a string in the 'dd hh:mm +:ss' format. my ( $time ) = shift; $time = int( $time ); my $newTime = sprintf( "%.2d ", int($time / 86400) ); $newTime .= sprintf( "%.2d", int(($time % 86400) / 3600) ); $newTime .= ':' . sprintf( "%.2d", int(($time % 3600) / 60) ); $newTime .= ':' . sprintf( "%.2d", int(($time % 3600) % 60) ); return ( $newTime ); } [download] Chris	[reply] [d/l]

Use Time::Seconds from the Time::Piece distribution. It allows you to do: `my $secs = Time::Seconds->new(1332443); printf "%d days, %d hours, %d min, %d sec\n", $secs->days, $secs->hours, $secs->mins, $secs->secs;` [download]	[reply] [d/l]
