Subject: Initialize time zone information before using it in wxGetTimeZone().
X-Git-Url: https://git.saurik.com/wxWidgets.git/commitdiff_plain/ff1e36afc063262750da38ca866784645be13520?ds=inline;hp=b296009869b608b12f415decd86c49bf5799a140

Initialize time zone information before using it in wxGetTimeZone().

We must call _tzset() before calling _get_timezone() as while this is normally
done implicitly by the other time functions, it might not have been done yet
if create a wxDateTime::TimeZone before calling any of them.

Closes #12700.
