I was just going to say "set the timezone for the running perl 
process".  On UNIX systems, at least, you would set the environment 
variable TZ.  For example, my system is set to GMT time, but I can 
get my program to log using Eastern Standard Time (EST) by setting TZ 
temporarily for the perl process:

         bash # date
         Wed Jul  5 14:28:48 GMT 2006
         bash # perl source.pl
         2006-186/14:28:55 INFO > source.pl Starting.....
         bash # TZ=EST5EDT perl source.pl
         2006-186/10:29:46 INFO > source.pl Starting.....

However, you have to know the right timezone abbreviation -- my 
system does not know "BST", so it continues to use GMT for the timezone.

         bash # TZ=BST perl source.pl
         2006-186/14:33:13 INFO > source.pl Starting.....

The correct abbreviation (on UNIX systems, at least), is "TZ=GMT0BST" 
(that's a zero not an "oh"):

         date # TZ=GMT0BST date
         Wed Jul  5 15:46:41 BST 2006

You can set the timezone at runtime from within your perl program, 
instead of before running it with the following:

         $ENV{'TZ'} = 'GMT0BST';

Hope that helps,
