Comments:		Conventions for representing date + time defined here are based on the ISO 8601 standard. Hours of the day should use 24-hour time (e.g. 2PM = 14:00:00). A time zone can be specified as described for ‘dates’ above, e.g. "1978-01-20T05:15:00Z, and "1978-01-20T05:15:00+5:00". If precision down to time of day is not possible or necessary, the hours, minutes, and seconds must still be provided due to schema constraints, but can all be set to “00” and ignored at the instruction of the message sender.
