System time in Service Desk does not match Server time, method of timestamping unclear

I see nowhere to configure the time showing in the top right of the service desk interface. It is not showing server time either. Server time is correct per our technical group, but the SD interface time is one hour off (perhaps due to recent change from/to daylight savings).

I would expect that the setting of the timezone on the Site entity should govern all requesters and technicians from that site, I have not yet been able to test a requester account to verify on that side but clearly this is not the way it works for technicians, where it is using personalization (though personalization is off by an hour, again probably due to daylight savings time).

PLEASE explain your model for time, and any configuration interfaces available to change time settings.

Thanks,
