Either an offset or format may be specified without the other, but if both are specified, the offset must be the first parameter. In this case, the time will be inserted into the page, and include seconds. An offset of -4 would display the time less four hours. This can be used to show times that vary between time zones. The HTML text that follows this command will be hidden during the specified time intervals.
Time intervals can be one minute, ten minutes or one hour.
Hours are specified as on a 24-hour clock. Leading zeros for single digits are required, and multiple times may be specified. Any HTML text that follows this command will be visible to users during the specified times. This is useful for displaying the date in another time zone. The format may be specified without specifying an offset.
