This special-purpose field is paired with UTCDateOnly to form a proper UTCTimestamp for bandwidth-sensitive messages. Valid values: HH = 00-23, MM = 00-59, SS = 00-5960 (60 only if UTC leap second) (without milliseconds). HH = 00-23, MM = 00-59, SS = 00-5960 (60 only if UTC leap second), sss=000-999 (indicating milliseconds).
