网上时间接口很多,但是源码里根本看不到常规的DateTime类型的时间。全是时间戳形式的时间。
这里提供一个接口:
http://www.hko.gov.hk/cgi-bin/gts/time5a.pr?a=1
取时间戳的前10位,转化成DateTime类型就可以了。前10位精确到秒。
public DateTime GetNowTime()
{
HttpHelper http = new HttpHelper();
HttpItem item = new HttpItem()
{
URL = "http://www.hko.gov.hk/cgi-bin/gts/time5a.pr?a=2",
Method = "GET",
};
HttpResult R = http.GetHtml(item);
Regex regex = new Regex(@"0=(?<timestamp>\d{10})\d+");
Match match = regex.Match(R.Html);
if (match.Success)
{
return GetTime(match.Groups["timestamp"].Value);
}
return DateTime.Now;
}
/// <summary>
/// 时间戳转为C#格式时间
/// </summary>
/// <param name=”timeStamp”></param>
/// <returns></returns>
private DateTime GetTime(string timeStamp)
{
DateTime dtStart = TimeZone.CurrentTimeZone.ToLocalTime(new DateTime(1970, 1, 1));
long lTime = long.Parse(timeStamp + "0000000");
TimeSpan toNow = new TimeSpan(lTime); return dtStart.Add(toNow);
}
