As usual, the IETF does a much better job than the ITU of making this
stuff available to the general public. See

 RFC 3339 "Date and Time on the Internet: Timestamps"
 http://www.potaroo.net/ietf/idref/rfc3339/

  This document defines a date and time format for use in Internet
  protocols that is a profile of the ISO 8601 standard for
  representation of dates and times using the Gregorian calendar.

Written via an open process; free for all to read, copy, distribute,
implement, or be involved in improvements to; with a complete ABNF
syntax specification; compatible with ISO 8601 but without a sufeit of
unnecessary alternative formats like ISO 8601. Includes a short
section on Leap Seconds, lots of info on time zones, etc.

LEAPSECS members Markus Kuhn and myself contributed suggestions to it.

And as I noted earlier, the IETF "ntp" working group is working on
updating the NTP standard (RFC1305 on NTP version 3, RFC2030 on SNTP
version 4), again in a relatively refreshing and open manner:

 http://ietf.org/html.charters/ntp-charter.html

http://www.potaroo.net/ietf/idref/rfc1305/

Join us and get a standard TAI spec for NTP!
