[Adhemerval Zanella]

clang-21 issues:

rtime.c:96:36: error: variable 'thetime' is uninitialized when passed as a const pointer argument here
      [-Werror,-Wuninitialized-const-pointer]
   96 |       res = __sendto (s, (char *) &thetime, sizeof (thetime), 0,
      |                                    ^~~~~~~

For SOCK_DGRAM the sendto send an uninitialized value.
