Question

我是Joda的新手，需要帮助。我试图将这个C＃代码转换为java。我一直在研究Joda-time以及查看库的文档。我正试图获得差异时代和UTC现在（）。但不知道如何使用Joda的Interval类来实现这一目标。这是C＃方法获取epoch并根据UTC now（）进行检查。然后得到两个日期之间的差异。

public static void AddApiAuthenticationHeaders(this HttpClient httpClient, HttpMethod httpMethod, string publicKey, string privateKey)
    {
        httpClient.DefaultRequestHeaders.Add("X-PSK", "thisisatestpublickey");//key:K-PSK

        DateTime epochStart = new DateTime(1970,01,01,0,0,0,0, DateTimeKind.Utc); //Getting UTC DATE since epoch
        TimeSpan ts = DateTime.UtcNow - epochStart; //get the current timestamp between now and january 1970
        string stamp = Convert.ToUInt64(ts.TotalSeconds).ToString(); //get the total seconds that have elasped

        httpClient.DefaultRequestHeaders.Add("X-Stamp", stamp);
        //research extension method
        string[] data = new string[] {publicKey, stamp.ToString(), httpMethod.Method };
        byte[] expectedSignature = data.ComputeHash(privateKey);

        httpClient.DefaultRequestHeaders.Add(HttpRequestMessageExtensions.SignatureHeaderName, Convert.ToBase64String(expectedSignature));
    }

这很好但现在我想在使用Joda的java中做同样的事情。

这是我一直试图做的，但我是要了解如何使用Interval类在两次中获得差异。

 DateTime epochStart = new DateTime(1970,1,1,0,0,0,0, DateTimeZone.UTC);

    Interval ts = new Interval(DateTime.now(DateTimeZone.UTC).getMillis(), epochStart.getMillis());

    String stamp = ts.toString(); // I know here is not right

我不是C＃专家，但是这段代码：

DateTime epochStart = new DateTime(1970,01,01,0,0,0,0, DateTimeKind.Utc); //Getting UTC DATE since epoch
TimeSpan ts = DateTime.UtcNow - epochStart; //get the current timestamp between now and january 1970
string stamp = Convert.ToUInt64(ts.TotalSeconds).ToString(); //get the total seconds that have elasped

似乎只获取自纪元以来的秒数并将其转换为字符串。所以这是等效的Java代码：

String stamp = String.valueOf(System.currentTimeMillis() / 1000);

如何使用Joda-Time隐藏C＃DateTime到Java DateTime
