--- Comment #1 from anlauf at gcc dot gnu.org ---
This is standard conforming and documented.
See https://gcc.gnu.org/onlinedocs/gfortran/SYSTEM_005fCLOCK.html
COUNT_RATE is system dependent and can vary depending on the kind of the
arguments. For kind=4 arguments (and smaller integer kinds), COUNT represents
milliseconds, while for kind=8 arguments (and larger integer kinds), COUNT
typically represents micro- or nanoseconds depending on resolution of the
underlying platform clock. COUNT_MAX usually equals HUGE(COUNT_MAX). Note that
the millisecond resolution of the kind=4 version implies that the COUNT will
wrap around in roughly 25 days. In order to avoid issues with the wrap around
and for more precise timing, please use the kind=8 version.
