if (remaindernum != 0 && remainderden != 0)

0. round the Utc_time to the second, the rounding function you need depends whether you want to round up, down or to the nearest value
1. Group by the value from step 0, getting the count

var wr = (HttpWebRequest)WebRequest.Create(uri);
SetHeader(wr, "GET", new Dictionary<tring,string> { {  "Content-Type", "x-text" }, ..});
if (stream != null && stream.Length > 0)
    using(var ws = wr.GetRequestStream())
        Copy(stream, ws, length);

public static void SetHeader(HttpWebRequest req, string method, Dictionary<string, string> headers)

req.Method = method;
foreach (var kv in headers)
{
	var k = kv.Key;
	var v = kv.Value;
	switch (k)
	{
		case "User-Agent":
			req.UserAgent = v;
