Get current number of hours and minutes using chrono::time_point

I have been trying to find an example using std::chrono which simply gets a chrono::time_point and extracts the number of hours and number of minutes as integers.

I have:

std::chrono::system_clock::time_point now = std::chrono::system_clock::now();

but I cannot find out how to then extract the hours and the minutes (since midnight)? I am looking for something like:

int hours = now.clock.hours();
