Detailed Description

A comprehensive set of functions for validating dates, times, leap years, and time zones.

Functions for validating dates, times and time zones.

This module provides functionalities to validate the correctness of date-time values, leap years, and time zone offsets. It also includes utilities for determining weekends and ensuring the validity of timestamp-based calculations.

Key Features:

Validate leap years using dates or timestamps.
Ensure the correctness of date components (year, month, day).
Verify the validity of time components (hour, minute, second, millisecond).
Check the validity of time zones and time zone structures.
Determine if a given timestamp or day corresponds to a weekend.

Usage Examples:

Check if a year is a leap year:
bool is_leap = time_shield::is_leap_year_date(2024);

time_shield::is_leap_year_date
constexpr bool is_leap_year_date(T year) noexcept
Checks if the given year is a leap year.
Definition validation.hpp:56
Validate a specific date:
bool is_valid = time_shield::is_valid_date(2024, 2, 29);

time_shield::is_valid_date
TIME_SHIELD_CONSTEXPR bool is_valid_date(T1 year, T2 month, T2 day) noexcept
Checks the correctness of the specified date.
Definition validation.hpp:230
Check if a timestamp falls on a weekend:
bool is_weekend = time_shield::is_day_off(1698249600); // Saturday, Oct 26, 2024

time_shield::is_day_off
TIME_SHIELD_CONSTEXPR bool is_day_off(ts_t ts) noexcept
Check if a given timestamp corresponds to a weekend day (Saturday or Sunday).
