Represents the international standard for the representation of date and time ( ISO 8601).
The string format is "YYYY-MM-DDThh:mm:ss.SSSZ" (excluding quotes).
A DateTime string consists of a date part, a time part, and an optional time zone information part. The time zone part may be a "Z", representing the Coordinated Universal Time (UTC) time zone (equals to +00) or a time zone offset (for example, +02:00).
If the time zone part is not present, the DateTime value represents local time.
The following pattern describes the DateTime format:
YYYY-MM-DDThh:mm:ss[.S+][Z|+-hh:mm]
Where:
YYYY = Four digit year
MM = Two digit month (01=January, and so on)
DD = Two digit day of month (01 through 31)
T = Time designator (shows start of time component)
hh = Two digits of hour (00 through 23, AM/PM not allowed)
mm = Two digits of minute (00 through 59)
ss = Two digits of second (00 through 59, leap second not allowed)
S+ = One or more digits of decimal fraction of a second
Z = Time is UTC
+- = + or - character indicating positive or negative offset to UTC
DateTime values are compliant with ISO 8601 "Representation of dates and times" but are restricted according to RFC 3339 "Date and Time on the Internet: Timestamps". The DateTime format is further restricted as follows:
- T and Z designators are upper case.
- . (dot) is used to indicate start of fractions of seconds (ISO 8601 also allows comma)
