pub unsafe extern "C" fn tzset()Expand description
Re-read TZ environment variable and configure global time zone.
Rust interface for the C function:
void tzset(void);The tzset function acts like tzalloc(getenv("TZ")), except it saves any resulting timezone object
into internal storage that is accessed by localtime_r, and mktime. The anonymous shared timezone
object is freed by the next call to tzset. If the implied call to tzalloc fails, tzset falls
back on Universal Time (UT).
