Refactor time utility functions for improved type safety and error handling

- Removed deprecated formatDate function.
- Enhanced formatWithZone to support TypeScript types for parameters.
- Updated getTimeZoneOffset to use TypeScript types.
- Improved formatWithDate for better error messages and type safety.
