TZ=CST6CDT is not a standard setting. On some hosts, it consults the tz database and will give you "generic" Central Time rules. On others it will consult a hardwired internal algorithm and will likely mess up. You'd be better off using a standard zoneinfo setting like TZ='America/Chicago'.
This shouldn't have anything to do with coreutils; it's a C library issue. _______________________________________________ Bug-coreutils mailing list Bug-coreutils@gnu.org http://lists.gnu.org/mailman/listinfo/bug-coreutils
