解决两个精度丢失问题

[1124863805]

subtractMinute(solar: Solar): number {
    let days = this.subtract(solar);
    const cm = this._hour * 60 + this._minute;
    const sm = solar.getHour() * 60 + solar.getMinute();
    let m = cm - sm;
    if (m < 0) {
        m += 1440;
        days--;
    }
    m += days * 1440;
    return m;
}

修改之后

subtractMinute(solar: Solar): number {
    const thisDateTime = new Date(this._year, this._month - 1, this._day, this._hour, this._minute, this._second);
    const solarDateTime = new Date(solar.getYear(), solar.getMonth() - 1, solar.getDay(), solar.getHour(), solar.getMinute(), solar.getSecond());
    
    const diffMs = thisDateTime.getTime() - solarDateTime.getTime();
    const diffMinutes = Math.floor(diffMs / (1000 * 60));
    
    return diffMinutes;
}
