[游戏开发]Unity 获取Unix时间戳

前言

在存储图片的时候使用时间戳可以很好的管理图片名称。

源码

    /// <summary>
    /// 获取时间戳（精确到秒）
    /// TimeTool.ConvertDateTimep(DateTime.Now)
    /// </summary>
    /// <param name="time">时间</param>
    public static long ConvertDateTimep(DateTime time)
    {
        return ((time.ToUniversalTime().Ticks - 621355968000000000) / 10000000);
        //等价于：
        //return ((time.ToUniversalTime().Ticks - new DateTime(1970, 1, 1, 0, 0, 0, 0).Ticks) / 10000000) * 1000;
    }
    /// <summary>
    /// 时间戳转为C#格式时间
    /// TimeTool.GetTime(TimeTool.ConvertDateTiemp(DateTime.Now).ToString())
    /// </summary>
    /// <param name="timeStamp">时间戳</param>
    /// <returns></returns>
    public static DateTime GetTime(string timeStamp)
    {
        if (timeStamp.Length > 10)
        {
            timeStamp = timeStamp.Substring(0, 10);
        }
        DateTime dateTimeStart = TimeZone.CurrentTimeZone.ToLocalTime(new DateTime(1970, 1, 1));
        long lTime = long.Parse(timeStamp + "0000000");
        TimeSpan toNow = new TimeSpan(lTime);
        return dateTimeStart.Add(toNow);
    }

效果

        //获取当前时间戳
        long unixTime = TimeTool.ConvertDateTimep(DateTime.Now);
        Debug.Log(unixTime);
        //将时间戳转换为DateTime
        Debug.Log(TimeTool.GetTime(unixTime.ToString()).ToString());
        Debug.Log(TimeTool.GetTime(unixTime.ToString()).Year);
        Debug.Log(TimeTool.GetTime(unixTime.ToString()).Month);
        Debug.Log(TimeTool.GetTime(unixTime.ToString()).Day);
        Debug.Log(TimeTool.GetTime(unixTime.ToString()).Hour);
        Debug.Log(TimeTool.GetTime(unixTime.ToString()).Minute);
        Debug.Log(TimeTool.GetTime(unixTime.ToString()).Second);
