+//! Time types similar to `std::time` types.

+//! However, the rust-embedded world tends to use `fugit` for time.  This has a Duration and
+//! Instant type, but they are parameterized by the slice used, and try hard to do the conversion
+//! at compile time.
+//!
+//! std has two time types, a Duration which represents an elapsed amount of time, and Instant,
+//! which represents a specific instance in time.
+//!
+//! Zephyr typically coordinates time in terms of a system tick interval, which comes from
+//! `sys_clock_hw_cycles_per_sec()`.
+//!
+//! The Rust/std semantics require Instant to be monotonically increasing.
+//!
+//! Zephyr's `sys/time_units.h` header contains numerous optimized macros for manipulating time in
+//! these units, specifically for converting between human time units and ticks, trying to avoid
+//! division, especially division by non-constants.
