PokerTracker

I'm sorry if i've not searched enough for an answer to this, but

I play at pokerstars, FTP, and bodog. Pokerstars and FTP operate in EST and Bodog (with the hands being grabbed with idleminer 1.12) operates in CST. This plays havoc with my hourly rate and total hours played in pokertracker. When I play for 2.5 hours across all three sites, it lists it as actually playing 3.5 hours.

Is there anyway to have PT move the timezone of the imported bodog hands to EST?

No, I'm afraid there isn't.

Would there be a way (or SQL query) where I could find out either

A: how many days I played at both bodog and any other site (FTP or pokerstars)?

or
B: how many days I played at a given site during a time period?
(with B I could then just take the overlapping days between number of days of bodog and another site)

If I could find this out, I could subtract one hour for each day played to get a more accurate time played then do the division myself for the hourly rate.

Thanks
Marty
