Sorry, the context is a lexer that's only intended for Date headers, and similar sources. I agree it's rational; that's the format I use. :-) I think Postel was wrong in a modern context and we should be less forgiving, https://tools.ietf.org/html/draft-thomson-postel-was-wrong-00, but on the other hand, the lexer should continue to handle Date formats in vogue thirty years ago that are still sitting in +inboxes. > There is no way to get from a numeric offset to a timezone unless one > makes bizarre assumptions (like only the US matters).

Right, so it's only turning PST on some old Date header into a `±hh:mm' that needs to remain. > Simplify this stuff into oblivion. I'll keep chipping away. I seem to be gardening at the moment. Getting rid of the dead, diseased, and crossing branches in order to see what's left. Thanks for the parsedate() pointer. -- Cheers, Ralph. https://plus.google.com/+RalphCorderoy _______________________________________________ Nmh-workers mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/nmh-workers
