Time Duration Calculations

The time durations support basic arithmetic operations, meaning you can multiply or divide a time duration by a number. Of course, you can compare time durations. I explicitly want to emphasize that all these calculations and comparisons respect the units.

With the C++14 standard, it gets even better; the C++14 standard supports the typical time literals.

Type	Suffix	Example
std::chrono::hours	h	5h
std::chrono::minutes	min	5min
std::chrono::seconds	s	5s
std::chrono::milliseconds	ms	5ms
std::chrono::microseconds	us	5us
std::chrono::nanoseconds	ns	5ns

How much time does my son Marius (17 years old) spend in a typical school day? I will answer the question in the following example and show the result in various time durations formats.
