Given that it is a class-A fuckup to send wrong dates, I will advocate that such timestamps SHOULD be ignored, but CAN be interpreted on a best-effort basis. Ohh, and also: GMT is (maybe!) what parliament decides in the UK, the correct "independent" timescale is called UTC. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
