To edit your time zone on your Pamoja Account: Go to your Pamoja Dashboard and select Account Icon > Manage Your Profile > Time Zone > Select Correct time zone according to Region. If the time zone you are trying to locate is not there, then select a different region with the same time zone.
If you have clicked on "Manage Your Profile" and the Time Zone section did not appear, click on the Show Sidebar tab and the section will pop up.
