2.3.1 CIM DateTime Type
The CIM DateTime type is a string that has the specific format that is specified in [DMTF-DSP0004] section 2.2.1.
Because DateTime types are strings, a provision is included in the encoding to ensure that they can be distinguished semantically.
Any datetime value type:
MUST be encoded as an Encoded-String, as specified in ABNF.
MUST contain a CIM qualifier whose name is CIMTYPE, whose type is string, and whose value is datetime.
If the CIM qualifier is omitted, the system MUST treat the DateTime type as a standard string.
