Recently my automatic timezone update stopped working. (ie it used to work but now it doesn't) Troubling thing is my mac detects the correct location (e.g. Golden, CO), but doesn't use this to update the timezone, despite "Set my timezone automatically..." being checked. See screenshot.
This issue now occurs with every network I have tried: work, home, airports, hotels, etc. And, I have already tried the usual set of fixes such as toggling auto timezone off and on, closing system preferences, rebooting, repairing permissions.
