It looks like the only distinction in behavior is the time scale; no implementation seems to have per-thread TIMEF state.

You could consider using a time step of seconds (for Intel/nvfortran compatibility), unless the runtime is being compiled for AIX (for XLF compatibility).  And having an environment variable to change these defaults.

Or, since TIMEF is easily implemented in portable standard Fortran, leave it up to users.
