Ensure real-time accurate scheduling and planning across UTC, server time, NTP-sourced time, user local time, and arbitrary time zones. Use for timers, reminders, cron planning, in X minutes or months or years calculations, absolute timestamp conversion, Chinese lunar date awareness, and cross-timezone coordination. Enforce exact duration fidelity so user values are never replaced by example values, compute target times in UTC first, and verify deltas before execution.

确保在UTC、服务器时间、NTP来源时间、用户本地时间及任意时区之间实现实时精确的调度与规划。适用于定时器、提醒、cron计划、X分钟后或月后或年后计算、绝对时间戳转换、中国农历日期感知以及跨时区协调。严格保证持续时间的精确性，用户输入的值绝不被示例值替代，首先在UTC中计算目标时间，并在执行前验证时间差。
