Messed up. If everything went on each individual time-fr<x>ame, you might get your paycheck 3 days late, or the baby would arrive before you got pregnant. You could be 2 hours early for work, then do a 19 hour shift. You could sleep five minutes while hours go by outside. Just wouldn't work.
CHAOS ! TOTAL CHAOS ! Everyone would be trying to control time to their advantage and that would NEVER work.<br />
IE: You are having a great time on vacation, so you want it to slow down and last much longer, and all of those around you that are working would want it to speed up and go faster.
It would be going by very fast, then slow at the good times
