Remarks

The following is the standard format for defining the time and date as defined in HTML 4.0 (and taken from the ISO reference 8601:1988).

Standard Date-Time Format
YYYY-MM-DDThh:mm:ssTZD

The following table shows the datetime syntax.

Syntax	Definition
YYYY	Four-digit year
MM	Two-digit month (01=January, etc.)
DD	Two-digit day of month (01 through 31)
hh	Two digit hour (00 through 23) (A.M./P.M. NOT allowed)
mm	Two digit minute (00 through 59)
ss	Two digit second (00 through 59)
TZD	Time zone designator

The following table shows values for the Time Zone Designator(TZD) above.

TZD syntax	Definition
Z	(Must be uppercase) Specifies coordinated universal time (UTC)
+hh:mm	Specified time is hh hours and mm minutes ahead of UTC.
-hh:mm	Specified time is is hh hours and mm minutes behind UTC.

If a generating application does not know the time to the second, it may use the value "00" for the seconds (and minutes and hours if necessary).

The standard specifies an uppercase "T" to indicate the beginning of the time element.

Note   This standard does not address the issue of leap seconds.

There is no functionality implemented for this property unless defined by the author.
