Oh, and you can't assume daylight savings time is an hour; it is sometimes two hours. You have to instead use the altzone variable to get the offset when you're in daylight savings time, but this again isn't available on all systems. I posted a pointer to the INN source a while back; I'm really not sure that anything less is sufficient to get full portability, although I certainly trust Paul Eggart's implementation. BTW, the yacc-based thing is exactly what I wrote the INN code to get rid of, since I didn't want a yacc dependency. -- Russ Allbery (rra@stanford.edu) <http://www.eyrie.org/~eagle/> - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.htmlReceived on Sun May 01 04:12:42 2005
