My job uses a 24 hour clock (aka, 2100 instead of 9 pm) When I am not at work I revert back to the standard 12 hour clock, like most non-military people use. My girlfriend, however, constantly uses the 24 hour clock (she just texted me about something that starts at '2155'). It's driving me nuts. If you are in the military I get it, you live it 24 hours a day and it's all you use. When I am away from work, though, I am AWAY from work and don't want to be reminded of my job. Anyway, not really a question, just me venting about my girlfriend that I have to meet at 2155, and the Cavs-Steph game starts at 1900...
