2.2.3.2.20.1 DATETIME Data Type
This data type is represented by a specific syntax, which takes one of the following formats:
#YYYYMMDDZ #
#YYYYMMDD HH:MM:SSZ#
The time is represented in Coordinated Universal Time (UTC) format. This portion is optional, and if it is missing, it is assumed to be zero. The Z at the end of the line indicates that the time is in UTC and is required even if the time portion is not present.
