Query based on Server offset TimeStamp

Hello, I have a mySQL database server in Florida USA (EST) and I want to do a query on a record in California, USA (PST) 3 hours earlier using PST instead of EST. I would like to add to my CORE page that offset of the timezone so I can use it in a query like: Select * FROM aTable WHERE ServerOffsetTimeStap >= Row_Start_TimeStamp AND ServerOffsetTimeStap <= Row_End_TimeStamp How would I do this? Appreciate any help you can offer. Thanks!
