2.3 dateTime Data Type
dateTime values are as specified in [ISO-8601].
All dates are given in Coordinated Universal Time (UTC) and are represented as a string in the following format.
YYYY = Year (Gregorian calendar year)
MM = Month (01 - 12)
DD = Day (01 - 31)
HH = Number of complete hours since midnight (00 - 24)
MM = Number of complete minutes since start of hour (00 - 59)
SS = Number of seconds since start of minute (00 - 59)
MSS = Number of milliseconds. This portion of the string is optional.
The T serves as a separator, and the Z indicates that this time is in UTC.
For example, 8:35 A.M. on December 25, 2000 would be represented as 2000-12-25T08:35:00.000Z.
Elements with a dateTime data type MUST be encoded and transmitted as [WBXML1.2] inline strings.
