You can create a custom localhost.tz. Lines 1 to 7 will be information about your timezone.
Instead of creating this file from scratch (from an empty text file), you can begin creating a file by modifying the existing settings. To do this, change to the pi\adm directory and extract the current settings using the command pidiag -tz to a text file. The result follows the above format. Save a copy of this file as a backup. You may then customize the output and re-save the file.
The customization will involve you removing all the rules in Lines 8 and higher since you do not want DST.
Thanks for the suggestion. I've tried this ten times and I still cant get it to work properly. I think that if I don't specify Lines 8 and higher for DST settings, perhaps if reverts to my server's DST settings which do use DST. I also tried to use a .tz file with a zero second offset during the DST period, but that didnt work either.
