Question

我正在使用HighStock图表link

它使用来自api apilink

的数据

第一个参数是日期，如

[
/* Sep 2009 */
[1252368000000,24.70],
..
]

这个日期格式是什么？如何获得这种格式是C＃？

Answer 1

这似乎是JavaScript date value，以1970年1月1日以来的毫秒数为单位提供。

您可以将其转换为DateTime several ways in C#。

例如（从上面的链接），您可以添加自JavaScript纪元以来经过的刻度。要从毫秒转换为刻度，请乘以10,000。因此，您可以写下以下内容：

new DateTime(1970, 1, 1).AddTicks(1252368000000 * 10000);

Answer 2

 /// <summary>
    /// Dates  represented as Unix timestamp 
    /// with slight modification: it defined as the number
    /// of seconds that have elapsed since 00:00:00, Thursday, 1 January 1970.
    /// To convert it to .NET DateTime use following extension
    /// </summary>
    /// <param name="_time">DateTime</param>
    /// <returns>Return as DateTime of uint time
    /// </returns>
    public DateTime ToDateTime( uint _time)
    {
        return new DateTime(1970, 1, 1).AddSeconds(_time);
    }

    /// <summary>
    /// Dates  represented as Unix timestamp 
    /// with slight modification: it defined as the number
    /// of seconds that have elapsed since 00:00:00 Thursday, 1 January 1970.
    /// To convert .NET DateTime to Unix time use following extension
    /// </summary>
    /// <param name="_time">DateTime</param>
    /// <returns>
    /// Return as uint time of DateTime
    /// </returns>

    public uint ToUnixTime(DateTime _time)
    {
        return (uint)_time.Subtract(new DateTime(1970, 1, 1)).TotalSeconds;
    }

Api中的未知日期格式
