Exactly!
What's the maximum duration for which this still works? I mean, does it
work if the differences if more than 24 hours for example?
Just for comparison the following perl script I hacked together for
demonstration purposes (not that we should use perl, but it's a proof of
concept):
#!/usr/bin/perl
my $t1 = time;
my $t1s = localtime($t1);
printf "t1 = $t1 ($t1s)\n";
my $t2 = $t1 + 86400 + 10800 + 1680 + 14;
my $t2s = localtime($t2);
printf "t2 = $t2 ($t2s)\n";
my $dt = $t2 - $t1;
my $dts = gmtime($dt);
($wday, $mon, $day, $time, $year) = split /[ ]+/, $dts;
$day -= 1;
printf "dt = $dt ($day.$time)\n";
Output:
t1 = 973495143 (Sun Nov 5 23:19:03 2000)
t2 = 973594037 (Tue Nov 7 02:47:17 2000)
dt = 98894 (1.03:28:14)

If it handles at least a couple of days, then I think it's reasonable.
Let's wait and see what obrien and jkh think about it...
