It only includes <sys/time.h> if _POSIX_C_SOURCE, _XOPEN_SOURCE or
_NETBSD_SOURCE is defined.

No, the parts protected by that #ifdef should not be available in a standalone
environment (that is for example bootloaders).

You did not describe what exact problem you are hitting. Therere are various
standards in several versions that describe different things that <time.h>
should export - maybe one of the ifdefs is wrong, but it is not the 
_STANDALONE part directly.
