Start of day in UTC timezone

Since all of our times are stored in UTC in our database (hopefully yours are as well!), getting all items created "yesterday" is not as straightforward as one would like. Since I have to look up how to get the correct UTC time, I figured I'd simply write it down.
from datetime import datetime, date, time, timedelta

utc_offset = datetime.utcnow() - datetime.now()

today_start = datetime.combine(date.today(), time())
today_start += utc_offset
today_end = today_start + timedelta(hours=24)
Hopefully this saves someone a little time.
