Using pfSense 2.4.2 (current version):

Access the webConfigurator GUI
Click on the menu icon at the very top right of the window
Select System
Select General Setup
Scroll about halfway down this options page to the timezone selections. You can choose either GMT +/- a specific value, or geographic locations, such as cities, etc.
After the changes, you may need to reboot the pfSense device before it starts reporting the correct time.

We have special situation with timezones here in Russia. Recently government had cancelled timesave shifting and it was no timeshifts for some time, but recently they decided to make one "last" timeshift backward.

All operating systems, including Windows 8 and Ubuntu, shifted time correctly and automatically.

But not pfSense: it shows time hour ahead.

How to fix? Probably I can edit timezone somewhere?

UPDATE

Sample commands:
```
$ date
Mon Oct 27 14:53:34 MSK 2014
$ date -u
Mon Oct 27 10:53:41 UTC 2014
```
Current currect time in MSK was 13:53.

  Does date -u show the correct UTC time? It seems pfSense doesn't actually have timezone data at OS level...

  See my update. Yes date -u shows correct UTC time, while date shows incorrect MSK time and it is different. Hence it HAS timezone data somewhere, just incorrect one

freebsd-update: Command not found. Trying to install freebsd-update with pkg also failed. This is pfsense router based on freebsd, may be it is limited distribution.

I have rewritten my answer for pfSense.
