      Bug#16057793 MAKE TEST FAILS
      
      Some of the tests for Field_timef were non-deterministic:
      it worked only for certain time zones.
      Fixed by ignoring the "yy-mm-dd" part of the datetime string.
     @ unittest/gunit/CMakeLists.txt
        Gmock uses NULL dereferences, add -Wno-null-dereference
        for compilers which support it.
     @ unittest/gunit/test_utils.cc
        Initialize THD::start_time.
