Clock freezes after changing timezone

[Steve Magoun]

The time in the datetime indicator freezes when you change the timezone.

To reproduce:
1) Note the current time in the datetime indicator
2) Change the system timezone, such as by clicking a different timezone in the datetime indicator menu or changing timezone in the date/time system settings app

Expected results:
The clock in the datetime indicator updates to show the current time in the new timezone. The clock continues to function normally, updating the minutes/hours as time progresses

Actual results:
The clock in the datetime indicator freezes. It does not update to the new timezone and no longer updates the minutes/hours - it stays frozen at the time it displayed when you updated the timezone.

The system time is not affected; running 'date' from a terminal displays the correct time. The menu in the datetime indicator will display the correct time. It's just the clock in the panel that is broken.

This is 100% reproducible on my system.

Marking High/Triaged since I have confirmed it and experienced it.

Could someone experiencing this issue please attach the output of "dconf dump /com/canonical/indicator/datetime/" ?

Specifically, I'm looking to see if there's any common pattern with whether or not the "Time in auto-detected location" box is checked.
