Here's a patch for fortran/41157.  dtime is documented
to return the execution since its last invocation.  For
x reasons that I don't fully understand, the current
implementation of dtime seems to skip saving the current
execution time on every other invocation.

It took me a while to figure out what's wrong with the original code. It stores the previous difference instead of the previous total time. Hilarity ensues.

Your patch is ok.

Cheers,
