melib/utils: remove tz arg in gettimeofday

nrxr · epilys · commit 800f751ccf16 · 2025-10-02T13:03:03.000+03:00
The timezone struct is deprecated in the gettimeofday function, void in
macOS and nullable in Linux systems, from the manpages of
gettimeofday(2) in macOS, the signature is:

  int
  gettimeofday(struct timeval *restrict tp, void *restrict tzp);

In ubuntu manpage:

  int gettimeofday(struct timeval *restrict tv,
    struct timezone *_Nullable restrict tz);

Passing a null parameter to gettimeofday matches the expectation in the
modern implementations of libc and avoids EXC_BAD_ACCESS errors in
inlined-optimized builds.
