I was just about to post this when I realized that module wtime_mod
lacked 'use omp_lib'. Sure enough, adding that line makes it work
properly. It's surprising, though, that the program as shown compiles
and runs without an error.

You're not really allowed to complain, not having specified "implicit none"
in the module wtime_mod.

I've worked with people who make a practice of declaring omp functions locally rather than by 'use omp_lib'. Intel Thread Checker raises a run time warning on this, even though the code is working correctly.
