Getting Time in MilliSeconds with Perl
I use something like this in perl to get the date and time:
Code:
use Time::localtime;
use Time::gmtime;
$tm = gmtime;
$time_str = sprintf "%04d-%02d-%02d %02d:%02d:%02d",
$tm->year + 1900, $tm->mon + 1, $tm->mday,
$tm->hour, $tm->min, $tm->sec;

It gives me something like this:

Code:
2010-08-26 06:50:55

I actually want the time down to the millisecond level. So I want something like:

Code:
2010-08-26 06:50:55.23

Any idea how I would get this?

posix::strptime

POSIX::strptime(3pm)					User Contributed Perl Documentation				      POSIX::strptime(3pm)

NAME

       POSIX::strptime - Perl extension to the POSIX date parsing strptime(3) function

SYNOPSIS

	($sec, $min, $hour, $mday, $mon, $year, $wday, $yday) = POSIX::strptime("string", "Format");

DESCRIPTION

       Perl interface to strptime(3)

FUNCTIONS

       strptime
	    ($sec, $min, $hour, $mday, $mon, $year, $wday, $yday) = POSIX::strptime(string, format);

	   The result for any value not extracted is not defined. Some platforms may reliably return "undef", but this is dependent on the
	   strptime(3) function in the underlying C library.

	   For example, only the following fields may be relied upon:

	    my ($min, $hour) = ( POSIX::strptime( "01:23", '%H:%M' ) )[1,2];

	    my ($mday, $mon, $year) = ( POSIX::strptime( "2010/07/16", '%Y/%m/%d' ) )[3,4,5];

	   Furthermore, not all platforms will set the $wday and $yday elements. If these values are required, use "mktime" and "gmtime":

	    use POSIX qw( mktime );
	    use POSIX::strptime qw( strptime );

	    my ($mday, $mon, $year) = ( POSIX::strptime( "2010/07/16", '%Y/%m/%d' ) )[3,4,5];
	    my $wday = ( gmtime mktime 0, 0, 0, $mday, $mon, $year )[6];
