Clock indicator on panel is updating infreqently

[iMac]

Recently I have noticed that my clock is frozen. Clicking on the frozen time in the indicator shows the current time in the dropdown (below the calendar), however the displayed clock in the panel is never updated.

Rebooting does not resolve the problem, but gives me an updated time displayed on the panel.

It is probably unrelated, however earlier this week I did notice some skew (that I have never seen before), confirmed it was the system clock on the command line and ran an ntpdate-debian to update. I dismissed the skew as the result of suspending too many times without reboot during which I had also toggled different CPU schedulers and frequency to influence system performance.

ntpdate-debian updated the time. Likely a coincidence, but I have been noticing this clock issue since I had this problem.

While I was submitting this bug, the panel indicator jumped forwards. So it appears to be an issue with the frequency of the update in the panel. It seems to get as much as a half hour behind, noting it just jumped from 10:21am to 10:57am as I was submitting the bug report.
