Progesterone suppositories timing?

Anyone know how rigid the times you’re supposed to take vaginal suppositories are? My nurse said it should be around the same time at day and night every day, but what if you’re traveling to another time zone? Say I take my evening one at 10pm ET, should I take it while I’m on my trip at 7pm PT to match the time? Or is it ok to do like 8 or 9PT and split the difference?

Thanks for the advice!
