gcc 12.2.0 on MinGW produces multiple warnings similar to the one below:
In function 'iso9660_set_dtime',
inlined from 'iso9660_dir_add_entry_su' at iso9660.c:782:3:
iso9660.c:353:44: warning: 'temp_tm.tm_isdst' may be used uninitialized
[-Wmaybe-uninitialized]
353 | time_zone = (p_tm->tm_isdst > 0) ? -60 : 0;
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~
This patch initializes the temp_tm structure to silence them.
