Is there a way to change the time zone on a form?
To resolve this, a user can either: Change the form to ‘Time Zone Independent’ which will retain the UTC value. This only works if the user does not need the form to display in user local time. Modify their script to detect the time zone offset used, recalculate back to UTC within the script, then take action.
When to use Time Zone independent or user local?
When an entity field is configured for ‘Time Zone Independent’ or ‘User Local’, it determines if the time zone offset is honored or not when the data is being retrieved from the store. However, the app form also has a setting of UTC or Local.
What happens when you change the date on a form to UTC?
The form display settings of UTC or Local will determine if the date displayed is calculated using the user’s time zone settings or if it displays it as the UTC value. Changing the form values to UTC instead of user local will prevent time zone offset calculations and will display the UTC date for the saved record.
How are time zones displayed in the Common Data Service?
If the data retrieved from the store is ‘Time Zone Independent’, but the form is set to local, the UTC data will be displayed as user local time based on the user’s time zone in their profile. The reverse is also true, a user local value from the store will be displayed as UTC if the form is set to UTC.
