I get the computer time lagging behind 10-15 ninutes.
It's nothing to do with the clock applet.

I left my computer turned on all night and now it is 15 minutes behind even though it should be syncing to 4 time servers.

I'd say it was missing interrupts except for the people who are running ahead.

ntpdate seems to KNOW that it is out:
