Simple way to calibrate hardware clock?
I'm reading through hwclock's manual, and I'm seeing that it's possible I don't know when the last time I set my system clock was, it couldn't have been too long ago, but now it's about 10-15 minutes fast. Is there any way to have it sync with any atomic clock online? Or would I have to actually find out that for every 1 day it's X seconds fast and set a CRON scheduled task?
