Detailed Description

template<class Clock, class Duration>
class duds::time::interstellar::TimePoint< Clock, Duration >

An extention to the C++ std::chrono::time_point template to make time points easier to work with.

I found the inclusion of the clock type to be rather bothersome since the DUDS library doesn't use types to track the origin of information. This class avoids that issue, and allows easier type conversions and cross-type assignments with a lot less typing. I find it is also eaiser to write code that doesn't result in compile-time errors using this template rather than using the C++ one directly.

Warning

This template allows implicit conversions that result in a loss of precision. For example, a time in nanoseconds can be converted to seconds. This is not the case with std::chrono::time_point.

Template Parameters

Clock	A clock class.
Duration	A duration class.
