This breaks the msvcrt tests:

../../../tools/runtest -q -P wine -M msvcrt.dll -T ../../.. -p msvcrt_test.exe.so time.c && touch time.ok
time.c:101: Test failed: Wrong date:Year   70 mon  0 yday   1 mday  2 wday 5 hour 0 min  0 sec  0 dst -1
time.c:112: Test failed: Wrong date:Year   70 mon  0 yday   1 mday  2 wday 5 hour 0 min  0 sec  0 dst -1
