The code is quite old, and I have been hacking at it for weeks trying to get it to work correctly. I have attempted to contact the original developer, but suspect his email is not been checked.

The code works fine in my limited testing.

Probably because you're passing the whole message id string to the
function instead of just the portion which is the datetime. Observe,
using your data:

$ perl test.pl 1RkkUB-000CAI-Ce
Starting with 1RkkUB-000CAI-Ce
Reduced to 1RkkUB
Seconds since Jan 1 1970: 1326235687
Tue Jan 10 14:48:07 2012
Tue Jan 10 22:48:07 2012

You have to strip all the extra cruft after and including the first
dash. Only the first 6 characters are significant for time
calculation.


Experiment with this:

#!/usr/bin/perl
use strict;
use warnings;

my $id = shift() || '1Rmrv2-0001v1-T6';
print "Starting with $id\n";
my $tm;
($tm = $id) =~ s/^([0-9a-zA-Z]{6})-[0-9a-zA-Z]{6}-[0-9a-zA-Z]{2}$/$1/ ?
print "Reduced to $tm\n" :
die ("Not proper format of message ID");
print "Extracted time portion: $id\n";

my $seconds = base62_to_decimal($id);
print "Seconds since Jan 1 1970: $seconds\n";
print scalar localtime($seconds),"\n";
print scalar gmtime($seconds),"\n";
