* Return monotonically increasing values.cheloha2018-03-022-27/+32
| | | | | | | | | | | | | | | | | | | | | The latest POSIX description of times(3) (and all others I can find) suggests that times(3) should return monotonically increasing values and that these values are only useful for real time interval measurement. All extant uses of times(3) confirm that this expectation is shared by application programmers. So, change gettimeofday(2) to clock_gettime(2)/CLOCK_MONOTONIC to ensure the return value increases monotonically, even if the system clock is changed by the superuser. Then update the manpage accordingly. While we're updating the manpage, move the information about the return values to a new RETURN VALUES section to bring times.3 up to speed with other library man pages. Manpage changes kicked around on tech@ with millert@ and jmc@. times.3 ok millert@ tb@ jmc@ times.c ok millert@ tb@

| | | | | | | | | | | | Complete in the sense that all POSIX *locale(3) and *_l(3) functions are included, but in OpenBSD, we of course only really care about LC_CTYPE and we only support ASCII and UTF-8.

OK kettenis@ dcoppa@, and guenther@ on an earlier version. Riding guenther@'s libc/librthread major bump.
