clj-time

Provides a functional, immutable API that wraps Joda Time, making date-time operations more expressive and less error-prone in Clojure, as shown in the core namespace with functions like date-time and plus.

Offers protocol extensions in clj-time.jdbc to use DateTime objects directly with SQL databases, reducing boilerplate for database operations without manual coercion.

Supports built-in ISO8601 and custom formatters for flexible date serialization, with examples in clj-time.format for parsing strings like '20100311' with custom patterns.

Enables complex time manipulations such as adding months or weeks, interval management, and generating periodic sequences, detailed in clj-time.core and clj-time.periodic.
