Detailed Description

Literal constants for time quantities.

These functions allow a simplified syntax for specifying a time quantity. In order to use these, their namespace must be used:

using namespace util::quantities::time_literals;

// definition of `util::quantities::second` constant:
constexpr auto t_s = 12_s;

// assignment (likely to a quantity) of
// `util::quantities::millisecond{500.0}`
t_s = 500_ms;
