The explain_adjtimex_on_error function is used to call the adjtimex(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_adjtimex(3) function, but still returns to the caller.

The explain_adjtimex_on_error function always returns the value return by the wrapped adjtimex(2) system call.
