I've been known to set it to pm instead of am time. But I usually set two alarms, one a lot earlier than I need to get up, and one close to the latest that I can get up as a backup. Wife gets mad and tells me to just set it when I have to get up because she hates the multiple snooze alarms going off. But I have to have lots of snooze time. I can't stand to have to jump right out of bed with no snoozing lol
