A very simple, no_std friendly time library for Rust that provides:
- a Time type that wraps a i128 representing nanoseconds since the Unix epoch
- a Duration type that wraps a i128 representing a number of nanoseconds
- const fn math operations for Time and Duration, plus basic core::ops trait implementations
Any conversion to calendar time and parsing and formatting of date/time strings should be accomplished with other libraries. This library just supports very simple high precision time calculations and nothing more.
