Can the evaluation / email times be changed by the sheet owner?

I understand that "Workflows set to run daily will evaluate changes to the sheet and execute between 12:00 AM and 11:59 PM in the sheet Owner’s timezone and messages will be delivered between 12:00 AM and 4:00 AM the next day."

Our sheet owner is based on the West coast of the US and all changes are complete by 3pm PST. But the notification are coming to our office in the EU at 11am. 3 hours after our days has started. We would like them sitting in our in box first thing.

So can we change the evaluation time in our sheet to say 6pm PST?
