Monotonic Implementation Difficulties

[PTaylor-us]

I am working on a unified time-type library for embedded applications embedded-time. There is one considerable pain point trying to make it compatible with the Monotonic trait for use with RTFM. That is the requirement that the Duration must implement a special TryInto to convert into the System Timer ticks. This use of TryInto feels inappropriate.

What I would like to suggest is instead have the System Timer implement some trait (let's call it Clock). This Clock trait would require a Fraction/Ratio indicating the precision of the clock. In that way a TryInto could be implemented to convert a duration to a different precision.

This would be roughly in line with how time is handled in the std::chrono library in C++.

I'm going to look into creating an example implementation of this structure, but any suggestions/comments would be much appreciated.
