Has that been considered before? See http://www.ietf.org/timezones/code/Theory In my opinion there will be a loss of flexibility if the information is published as a RFC. Regards, -sm

[PATCH] Updates for Chile 2013
by Petr Machata March 4, 2013

--- Hi there, this is a patch for the Chile update that others have brought up. I decided to apply the transition dates to single years only--the DST policy is reevaluated every year anyway.

tz2013a on github now, not yet at IANA
by Paul Eggert March 1, 2013

March 1, 2013

At this point I consider the tz version on github to be the next official release. I've updated its version number accordingly, to tz2013a. I am still working through security hassles getting it officially installed at IANA. The current hangup is an incompatibility between my secure client (64-bit GNU/Linux) and IANA's authenticator (something written by Juniper that insists on 32-bit Java), which we have not yet ironed out.
