When creating an HL7 message definition, map the following HL7 datatypes to the appropriate datatypes.
The HL7 Date, HL7 Time, and HL7 Timestamp datatypes do not support varying precision among different message instances. You must select a specific format for each of these datatypes in your HL7 message. If you need to support different date/time precisions in the same message definition, use the String datatype instead. In this case, validation will not reject incorrectly formatted dates.
