Wrong by 1h is not pinpoint accuracy (i think). Here is a patch that describes what i mean: --- ./cygwin-snapshot-20110608-1/winsup/utils/cygcheck.cc 2011-04-07 08:09:28.000000000 +0200 +++ ./cygwin-snapshot-20110608-1.new/winsup/utils/cygcheck.cc 2011-06-10 19:31:59.000000000 +0200 @@ -1398,7 +1398,9 @@ printf ("\nCygwin Configuration Diagnostics\n"); time (&now); - printf ("Current System Time: %s\n", ctime (&now)); + /* UTC is better than local time for reference purposes, and also does + not depend on TZ, which is problematic in certain cases under msvcrt.dll */ + printf ("Current System Time (UTC): %s\n", asctime (gmtime (&now))); OSVERSIONINFOEX osversion; osversion.dwOSVersionInfoSize = sizeof (OSVERSIONINFOEX); Also to be considered similar patches for the other programs that don't link with cygwin1.dll, if necessary.
