Set OneCalendar timezone

My use case:  I am in New York and have meetings next week in LA.  I need to see the LA times of the meetings for easier planning.  In fact, I am currently writing an email to LA colleagues about this, so I need to set OneCalendar to LA time to see my schedule while writing -- without having to go into Windows settings to change the whole device time.  I don't afterall want my email to have an LA time stamp, I just want to see the meetings correctly.  Sure I can just subtract 3 from what OneCalendar shows, but this is what computers are good at.

So idea:   button to "set OneCalendar timezone"  (default could still be device time)
