The 24 Hour Clock

The 24 hour clock totally kicks ass. Use it. If you don't understand how it works, get a vasectomy. The AM/PM stuff is just bullshit. Next time you use a time in writing, use the 24 hour clock. Everyone will understand you immediately without any confusion. It isnt very necessary in conversation, however, and would even sound a little stupid. Just like using AM/PM in conversation sounds retarded. In case you didn't know, you should say "3 in the afternoon" instead of "3 PM" or "15 o'clock". But for emails, letters, meeting times organized and etc, all times should be clearly using the 24 hour clock. Put a leading zero in if you have to. -> "Meeting at 09:00. Pacific Standard Time." Not only will no meathead be confused about that time, it gives the impression that you don't mess around with times and you will seriously go apeshit military-style if people aren't punctual. The 24 hour clock increases clarity, saves space and a few CPU cycles. Anybody that refuses to switch has way too many chromosones.

Also, make it a habit to write dates in year-month-day format. yyyy-mm-dd hh:ss. Listen or I'll smack you.
