CFDate

CFDate is a data type in the Core Foundation framework of Apple's operating systems, including macOS and iOS. It represents a specific point in time, analogous to the `NSDate` object in the Foundation framework. CFDate objects are immutable, meaning once created, their value cannot be changed. They are typically used for tracking dates and times, such as timestamps for file creation or modification, or for scheduling events.

Core Foundation dates are often used in conjunction with other Core Foundation types and C-based APIs. They can be created from various sources, including other date representations or by specifying components like year, month, day, hour, minute, and second. Conversion between CFDate and other date and time formats, such as Julian dates or specific string representations, is possible through various Core Foundation functions. Memory management for CFDate objects, like other Core Foundation objects, follows a reference counting system. Developers are responsible for managing the creation and release of CFDate objects to prevent memory leaks. While `NSDate` is more commonly used in modern Objective-C and Swift development, `CFDate` remains relevant in lower-level C APIs and for interoperability with older codebases.
