The Linux man page for times() mentions this special behavior, how it
isn't portable, and even advises against using the function:

"On Linux, the buf argument can be specified as NULL, with the result
that times() just returns a function result. However, POSIX does not
specify this behavior, and most other UNIX implementations require a
non-NULL value for buf."

"[...] a portable application would be wise to avoid using this value.
To measure changes in elapsed time, use clock_gettime(2)
instead."

One might argue that it would be nice to emulate the Linux behavior,
but it's not required by POSIX.
