Domain Time Zone
Each domain can be associated with a time zone, and all transactions in the domain are assigned system dates and times based on that time zone. Use the Time Zone field in the Domain record to specify the time zone that applies to a particular domain.
When using your QAD application, if you change to another domain with a different time zone, that time zone now applies and any transactions you create in that domain are assigned dates and times relative to the time zone you have switched to. When calculating the time zone offset, the system also determines whether daylight savings time is in effect for that time zone, and adjusts accordingly.
If the Use User’s Time Zone for Default Domain field is activated in Database Control (36.24.1), your default time zone from User Maintenance (36.3.1) is used when you switch to your default domain. The Use User’s Time Zone for Default Domain field is deactivated by default. See Setting a Default Time Zone.
