All date and time values that are mapped to Date or Date & Time Keyword Types in OnBase must conform to the dateTime data type in the FHIR specification, which follows the ISO 8601 date and time format standard. The date/time value stored into OnBase is converted to the local time zone of the OnBase database.
If a mapped value is not in the valid date/time format, the value will not be stored in OnBase, and an OperationOutcome warning will be returned.
