C++ program to get the current time

This function or variable may be unsafe. Consider using any other ....

I am using Visual Studio 2019

You can use std::chrono::system_clock::now() function to get the current time point.

ctime and localtime are unsafe as these returns pointer to static data.

Therefore, ctime_s and localtime_s are provided in VS2019 (also in some earlier versions), which takes a pre allocated pointer in which value need to be returned and hence safe to use.
