Detailed Description

Time and date handling utilities.

Provides classes for time duration, points in time, and UTC date/time handling. Includes support for:

• Time durations with various units (nanoseconds to days)
• Time points representing moments in time
• UTC date/time with calendar operations
• Literals for time durations

Key features:

• High precision time representation (nanoseconds)
• Calendar calculations (leap years, days in month, etc.)
• Platform-independent time operations
• Comparable, hashable, and printable interfaces
