Its value space is described as the combination of date and time of day in the Chapter 5.4 of ISO 8601. Valid values are in the format YYYY-MM-DDTHH:MM:SS.s where YYYY = 0000-9999 year, MM = 01-12 month, DD = 01-31 day, HH = 00-23 hour, MM = 00-59 minute, SS = 00-60 second (60 only if UTC leap second), and optionally one or more digits representing a decimal fraction of a second. The punctuation of "-", ":" and the string value of "T" to separate the date and time are required. The "." is only required when sub-second time precision is specified. Leap Seconds: Note that UTC includes corrections for leap seconds, which are inserted to account for slowing of the rotation of the earth. Leap second insertion is declared by the International Earth Rotation Service (IERS) and has, since 1972, only occurred on the night of Dec. 31 or Jun 30. The IERS considers March 31 and September 30 as secondary dates for leap second insertion, but has never utilized these dates. During a leap second insertion, a UTCTimestamp field may read "1998-12-31T23:59:59", "1998-12-31T23:59:60", "1999-01-01T00:00:00".

The fractions of seconds may be empty when no fractions of seconds are conveyed (in such a case the period is not conveyed), it may include 3 digits to convey milliseconds, 6 digits to convey microseconds, 9 digits to convey nanoseconds, 12 digits to convey picoseconds; Other number of digits may be used with bilateral agreement.
