Default Re: The 24 Hr clock system

Trust me, for those who have to guess what time it is in other time zones to try and catch people when they're up and about, 24 hour clocks make it a LOT easier.
For example: It is 9:25pm here on AEST (GMT +10:00), if I need to figure out what time it is for someone over in (say) Arizona (GMT -7:00), I turn 9:25pm in to 24-hour (which makes it 21:25), then deduct 17 hours (10 hours to GMT, then the 7 to Mountain Time) which makes it 04:25 or 4:25am in Arizona. (12-hour AM/PM figures given for those who can't follow 24-hour or Military Time)

Mentally and mathematically, this is MUCH easier than trying to figure it out purely in 12-hour with AM/PM. Besides, you usually DON'T things like "meet me in the mess hall at 1800 hours." UNLESS you're in some form of the military (ie: army, navy, air force).
The only problem you run into is whether DST is in effect in either the timezone you're working from or the timezone you're working to.
