Problem:
An error about _CRT_SECURE_NO_WARNINGS when I use the std::localtime() function for getting the current systime.

Solution:

1. Use an alternative feature function in C++.
2. add this line at the first line.

#define _CRT_SECURE_NO_WARNINGS

3. add _CRT_SECURE_NO_WARNINGS on the pre-processor(project>properties>C/C++>preprocessor)
