Implemented the following: - `asctime_r()` - `asctime()` - `localtime()` - `localtime_r()` - `ctime()` - `ctime_r()` Specifically: - the implementation of `localtime()` & `localtime_r()` simply wraps around the gmtime() & gmtime_r() functions, the results are always expressed as UTC. - `ctime()` is equivalent to `asctime(localtime(clock))`, it inherits the limitation of `localtime()` as well, which only supports UTC results currently. Added tests for these newly implemented functions. Signed-off-by: Yong Cong Sin <ycsin@meta.com> Signed-off-by: Yong Cong Sin <yongcong.sin@gmail.com>
