Time adjustment

More a quality of life issue, but is there a way to adjust the time accurately? Am I missing something?

I'm US Pacific Time. The printer is off by 4hrs.

I can't set PT zone, I can only adjust the printers base timezone manually by 4hrs. It's more confusing that you can set automatic adjustment for summer time, but not global time zone.

(While not important, I also find it weird that you can only adjust minutes in 30 and 45 increments...what's the utility of that?)
