解决Clock skew detected

问题:在编译过程中会出现类似的以下warning
[ 92%] Building C objectCMakeFiles/dyna.x.dir/mystrings/StrEdit.c.o
[100%] Building C objectCMakeFiles/dyna.x.dir/mystrings/mystring.c.o
Linking C executable dyna.x
make[1]: Warning: File `StrEdit.c' has modification time 36 s inthe future
make[2]: warning: 
Clock skewdetected.  Your build may be incomplete.

原因:
in regards to the below warning...
Warning message: Clock skew detected. Yourbuild may be incomplete.

These warnings can occur when the clock on the build machine is outof sync with the timestamps on the source files. Other errors,apparently unrelated but in fact caused by the clock skew, canoccur along with the clock skew warnings. These secondary errorsmay tend to obscure the fact that the true root cause of theproblem is an out-of-sync clock. For example, an out-of-sync clockhas been known to cause an old version of javac to be used tocompile some files, resulting in errors when the pre-1.4 compilerran across the new assert keyword in the 1.4 source code.
If you see these warnings, reset the clock on the build machine,run "gnumake clobber" or delete the directory containing the buildoutput, and restart the build from the beginning.

解决:
find . -type f | xargs -n 5 touch
make clean
make
