That's from IEEE Std 1003.1-2017 (which is a revision of 1003.1-2008). We support 1003.1-2004 per .../devel/hacking.txt http://pubs.opengroup.org/onlinepubs/009695399/functions/timer_create.html includes a note "TMR" that says: "The functionality described is optional. The functionality described is also an extension to the ISO C standard." So timer_create is optional for the minimum POSIX version that we support.
