Since “Time of Day” is just a label, why isn’t everywhere on GMT (for example)? Does it really matter if a business hours are 9 to 5 or 1400 to 2200! I don’t think so. As someone who had to work with people in different time zones, (and in one job supervise people around the globe), scheduling “thru” time zones was a mess. There’s a reason the military use Zulu (aka GMT) for all orders. Sigh!
