How do I configure the Analytics session time zone?
Purpose
Perform this procedure to configure the time zone for the analytics session. If no time zone is selected, the browser time zone is used for report generation.
The session time zone defines the current time displayed in Analytics. The time zone used for aggregation, that is, the definition of when a day ends, is the aggregation time zone. The session time zone and the aggregation time zone must be the same. See also How do I configure analytics aggregation?.
