    Specification PSE52 Realtime Controller 1003.1-2003 System Product Standard
    Location in Spec Chapter 13 Headers <semaphore.h>
    Problem Summary Visibility of symbols in <time.h> in header file <semaphore.h>
    Problem Text POSIX.1-2004 did not allow <semaphore.h> to make symbols from <time.h>
    visible, but POSIX.1-2017 seems to allow it.

    /tset/rt.hdr/misc/semaphore/T.semaphore 21 Failed
    Test Description:
    For POSIX01 mode:
    When _POSIX_C_SOURCE is defined with the value 200112L and
    no
    other feature test macros except _POSIX_SOURCE are defined,
    no
    other symbols than those defined or reserved by POSIX.1-
    2001/XSH6
    (not including the XSI option) are made visible.
    For POSIX08 mode:
    When _POSIX_C_SOURCE is defined with the value 200809L and
    no
    other feature test macros are defined, no other symbols
    than those
    defined or reserved by POSIX.1-2008/XSH7 are made visible.
    For UNIX98 mode:
    When _XOPEN_SOURCE is defined with the value 500 and no
    other
    feature test macros except _POSIX_SOURCE and
    _POSIX_C_SOURCE<=199506L are defined, no other symbols than
    those
    defined or reserved by XSH5 are made visible.
    For UNIX03 mode:
    When _XOPEN_SOURCE is defined with the value 600 and no
    other
    feature test macros except _POSIX_C_SOURCE<=200112L are
    defined,
    no other symbols than those defined or reserved by POSIX.1-
    2001/XSH6 (including the XSI option) are made visible.
    For UNIX10 mode:
    When _XOPEN_SOURCE is defined with the value 700 and no
    other
    feature test macros except _POSIX_C_SOURCE<=200809L are
    defined,
    no other symbols than those defined or reserved by POSIX.1-
    2008/XSH7 are made visible.
