Strategy Tester unable to match data after server change to a different time zone

 

Strategy Tester no longer works after my broker recently changed its live server from GMT-5 to GMT+2. I've been having to switch back and forth to the old GMT-5 server to test, but that server now has completely gone away, and I have no means to test my EA.

Please note that I am not talking about the offset hours; that is already adjusted for during the test.

Does anyone know why time zone makes any difference to Strategy Tester, and know if there is a script available to convert this old data and make it look like it is from the server at GMT+2?

Thanks for any hint.
