Date/Time Stamps off by 7 hours

I’m working on upgrading from 6.0 to 8.0. I am testing the upgrade side-by-side with a copy of the live environment. Both DBs and websites are on the same server. When I create a new Third Party in both systems and go to the “Log” tab, I’m seeing 2 completely different times between the 2 sites. The “Server” date and time are the same and are correct. However, the “Client” date and time are different. The 6.0 version is correct, but the 8.0 version is ahead by 7 hours. Is there something I need to adjust in the configuration in the 8.0 version so it shows the correct date and times when I make changes? This doesn’t just happen with Third Parties, it happens everywhere in the system.
