4//! A crate for more or less frequently used time parsing and formatting
5//! functionality.
6//!
7//! The crate revolves around the `std::time::SystemTime` type in that
8//! we attempt to convert into that or use this as the base to convert
9//! from. We treat such a time as having no associated time zone. Think
10//! of it as being in UTC.
