What is the time zone in which responses to SOAP requests return data?
Oracle Service Cloud, All supported versions
When performing a SOAP Get request, the time zone used for date/time values is UTC - the values are normalized and are returned in the following format: 20050110T04:00:00Z.
However, when you perform a RunAnalyticsReport request, the time zone used is the Interface time zone (set in the TZ_INTERFACE hidden configuration setting) and the values are returned in the following format: '2016-02-15 20:48:34'. Specifying a different time zone in the report settings will not affect this behavior.
More information about date/time handling in Connect Web Services for SOAP can be found in the Date / Time Handling section of the Connect Web Services for SOAP documentation:
