A CIM datetime may contain a date or an interval. CIMDateTime is an intrinsic CIM data type that represents the time as a string with a fixed length. 
    A date has the following form:
    yyyymmddhhmmss.mmmmmmsutc

    Where

    yyyy = year (1-9999)
    mm = month (1-12)
    dd = day (1-31)
    hh = hour (0-23)
    mm = minute (0-59)
    ss = second (0-59)
    mmmmmm = microseconds
    s = '+' or '-' to represent the Coordinated Universal Time (UTC) sign
    utc = offset from Coordinated Universal Time (UTC)
        (same as Greenwich Mean Time(GMT) offset)

    An interval has the following form:

    ddddddddhhmmss.mmmmmm:000

    Where

    dddddddd = days
    hh = hours (0-23)
    mm = minutes (0-59)
    ss = seconds (0-59)
    mmmmmm = microseconds
Note: Intervals always end in ":000". This distinguishes intervals from dates. CIMDateTime objects are constructed from String objects or from other CIMDateTime objects. Character strings must be exactly twenty-five characters in length and conform to either the date or interval format. CIMDateTime objects that are not explicitly initialized will be implicitly initialized with a zero time interval: 00000000000000.000000:000 */ class PEGASUS_COMMON_LINKAGE CIMDateTime { public: /** Creates a new CIMDateTime object with a zero interval value. */ CIMDateTime(); /** Creates a new CIMDateTime object from a string constant representing the CIM DateTime-formatted datetime.
