Your server (as did mine) floats away from the real time pretty badly. Right now it's about 15mins fast. You should configure your ntp and have it start on boot. It's also worth noting that ntp won't auto adjust your clock if it's more than 1000s(16m40s) out of sync, that took me at least a week to figure out why it was never syncing properly. It got so bad at one point that I think I had to override that threshold value.
