ISO-8601 dates are unambiguous. http://en.wikipedia.org/wiki/ISO_8601 the difficulty with them and their clear YYYY-MM-DD format, like the metric system or Celsius, is in getting them understood, adopted, and used by Americans who insist on using two-digit years and a rather odd MM-DD-YY ordering. It's a hopeless lost cause; there's no mileage in it. Lloyd Wood http://sat-net.com/L.Wood/ has a separate rant about the two-digit years still in use in orbital two-line element sets. With a wraparound in 2057 because Sputnik-1 launched in 1957. Or possibly 2058, because Explorer-1 launched in 1958. And that, like TLEs and NORAD, is American. ________________________________________ From: ietf [ietf-bounces@xxxxxxxx] On Behalf Of Dave Cridland [dave@xxxxxxxxxxxx] Sent: 03 December 2013 05:37 To: ietf@xxxxxxxx Discussion Subject: IETF Meeting Scheduling I note with some confusion that there may be an error in the IETF "Important Dates" page, regarding the dates of the Honolulu meeting which is, as I'm sure you'll all agree, an important date if ever there was one, which we'll all be trying to sneak onto our corporate travel junkets as early as possible. Imagine my confusion, then, when I realised with horror that it'd already passed: IETF 91: November 9 - 14, 2013, Honolulu, HI, USA Luckily, I then realised the correct dates were listed below, more consistently with the other dates on the page, and I've merely missed the first month: 2014-11-09 - 2013-11-14: 91st IETF Meeting in Honolulu, HI, USA. Although clearly the wrong way around, I congratulate those organizing the 2014 meetings for extending the highly congested week; although for that length of time I may need to pack extra socks. Dave.
