I'm getting somewhat troublesome output from the below STC. It seems as if gmtime mucks with something, or that localtime is not filling in everything it needs to? ------------------8<---(zone.c)--------- #include #include int main(void) { char zone[6]; struct tm *tm; time_t now = time(NULL); tm = localtime(&now); strftime(zone, sizeof(zone), "%z", tm); printf("%s %d %d\n", zone, timezone, tm->tm_isdst); tm = localtime(&now); strftime(zone, sizeof(zone), "%z", tm); printf("%s %d %d\n", zone, timezone, tm->tm_isdst); tm = gmtime(&now); tm = localtime(&now); strftime(zone, sizeof(zone), "%z", tm); printf("%s %d %d\n", zone, timezone, tm->tm_isdst); return 0; } ------------------8<-------------------- I expect three equal lines, e.g. +0200 -3600 1 +0200 -3600 1 +0200 -3600 1 but I get this on Cygwin: +0200 -3600 1 +0200 -3600 1 +0000 -3600 1 $ cygcheck -c gcc4 cygwin Cygwin Package Information Package Version Status cygwin 1.7.9-1 OK gcc4 4.3.4-4 OK FWIW, I have tested the STC on Linux and Solaris 10 and they behave as I expected...
