  • Each web user on the project may set their own perferred preferred timezone that overrides the project timezone when they're looking at reports. If the same user wanted to see India data in IST and South America data in the correct South American timezone, then they would have to change their own preferred timezone override between looking at one location's data and looking at the other. If there are certain people who only look at India data or only look at South America data then this could be helpful for them
  • When you export data to excel, date/times will always be in UTC / +00:00 timezone / "zulu time", regardless of the project's timezone. It was decided to do this for exactly this reason: if you have different timezones at play, then as much as a pain as it is, it's still much easier if everything is consistently reported in this standard time than if it's unclear which timezone a particular date/time is in.

Dates and Times Calculated Within A Form

When a date or time is calculated within a form in your application, the timezone used will be based on the browser's (WebApps) or phone's (mobile) timezone settings, not the project space's timezone settings. For more information on the date and time functions available within CommCare forms, refer to the CommCare Functions wiki and the Calculations with Dates and Times wiki.
