The gmtime_r() function converts the calendar time pointed to byclockinto a broken-down time expressed asCoordinated Universal Time (UTC). The broken-down time is stored in the structure referred to byresult. The gmtime_r() function also returns the address of the same structure. ...

In many implementations, including glibc, a 0 in tm_mday is interpreted as meaning the last day of the preceding month. According to POSIX.1-2001, localtime() is required to behave as though tzset(3) was called, while localtime_r() does not have this requirement. For portable code, ...
