    I have a question about the behaviour of system_clock.

    The Fortran 2018 spec just says it returns a “processor-dependent value” which is “incremented by one for each clock count until the value
    COUNT_MAX is reached and is reset to zero at the next count”.

    Why is nvfortran so different?

    This code is running on the GPU, right? That very likely does not maintain
    its own system clock.
