 //! ## Feature Flags
 //! - `std`: Enable integration with standard library. Disable this feature for `no_std` support. This feature is enabled by default.
 //! - `arbitrary`: Enable integration with crate `arbitrary`. All types on this crate will implement `trait Arbitrary`.
+//! - `chrono`: Enable integration with crate `chrono`. Time related types implement conversions to/from their `chrono` equivalent.
