Spooky,
There are a bunch of perl modules for this type of thing. There is new school DateTime and there is old school Date::Manip. Then there is the roll your own school (untested). 
#!/usr/bin/perl
use strict;
use warnings;
use Time::Local;

my $ts1 = '2000-01-01 00:00:00.000000';
my $ts2 = '2009-03-05 18:59:11.674653';

my $elapsed = time_diff($ts1, $ts2);
sub time_diff {
    my ($ts1, $ts2) = @_;
    my ($yr1, $mon1, $day1, $hr1, $min1, $sec1) = unpack('A4xA2xA2xA2x
+A2xA2', $ts1);
    --$mon1;
    my $micro = substr($ts1, 19);
    my $epoch1 = timelocal($sec1, $min1, $hr1, $day1, $mon1, $yr1);
    $epoch1 += $micro;
    my ($yr2, $mon2, $day2, $hr2, $min2, $sec2) = unpack('A4xA2xA2xA2x
+A2xA2', $ts2);
    --$mon2;
    $micro = substr($ts2, 29);
    my $epoch2 = timelocal($sec2, $min2, $hr2, $day2, $mon2, $yr2);
    $epoch2 += $micro;
    return $epoch2 - $epoch1;
}
