Detailed Description

Main namespace for the Time Shield library.

Contains all public types, constants, and functions of the library. The API provides:

• time and date structures
• parsing and formatting
• conversions between representations (seconds/milliseconds, calendar fields, etc.)
• timezone utilities (named zones, UTC offsets)
• validation helpers
• timers and scheduling utilities
