I just finished with my setup (Already setup the timezone & localization through ospi config), however in the web application whenever I make a change and safe it, it commits.
My problem is:
1) the timezone shows -5 Boston, MA. However I’m Boston, ZA (Cape Town, Boston, South Africa) GMT+2. I’m unable to change the timezone in the web app it is greyed out.
2) I read on the forums some people said that they rebooted the device to get it to work. However everytime I reboot the Raspberry Pi my Web application options are back to default.
Let me comment your issue. I have never seen the time zone tab other than grey however the timezone was automatically set according to selected location on the map.
The timezone settings in Linux has no effect on the GUI. They are independent.
From jeeva’s screen shot, it looks like the location is still the factory default (Boston,MA), and so the time displayed on the screen shot is UTC-5:00 time. To change it, just go to Edit Options and change the location.
