一般获取网络时间的方法都是去找到个可以显示时间的网址，这里列几个比较可靠的：
http://www.beijing-time.org/time15.asp
http://api.k780.com:88/?app=life.time&appkey=10003&sign=b59bc3ef6191eb9f747dd4e83c99f2a4&format=json

不过这些可能会随着人家网址变更或接口收费等更新导致失效。

今天下午专门研究了下怎样可以比较可靠的获取网络的时间的问题，发现网上有个java写的代码可以根据任何一个网站访问返回的头信息里取时间，相当于去获得这个网站的服务器时间，这样的话我们去获取百度阿里等大网站的服务器时间，这样就比较可靠了，而且一般也不会出现不可访问的问题。研究了下得到了GMT时间，然后又花了不少时间通过js中转终于可以得到我们的标准时间了。如果有谁有把GMT时间简便转换为标准北京时间的代码的话请提供下。

Private Sub Form_Load()MsgBox getWebDatetime
End Sub'方法一，根据个别网址得到时间，由于网站不确定性可能会更新导致失效。不推荐
Private Function getWebDatetime() As StringDim strData As StringDim reg As ObjectDim XmlHttp As ObjectSet XmlHttp = CreateObject("Microsoft.XMLHTTP")XmlHttp.Open "GET", "http://www.beijing-time.org/time15.asp", FalseXmlHttp.SetRequestHeader "If-Modified-Since", "0"XmlHttp.sendstrData = StrConv(XmlHttp.ResponseBody, vbUnicode)Set XmlHttp = NothingSet reg = CreateObject("vbscript.regExp")reg.Global = Truereg.IgnoreCase = Truereg.MultiLine = Truereg.Pattern = "[\s\S]*?(\d{4})[\s\S]*?(\d+)[\s\S]*?(\d+)[\s\S]*?(?:\d+)[\s\S]*?(\d+)[\s\S]*?(\d+)[\s\S]*?(\d+);.*"getWebDatetime = reg.Replace(strData, "$1-$2-$3 $4:$5:$6")
End Function方法二，根据网上提供的一些接口提供。推荐
'直接调用getWebDatetime获取网络日期时间
Public Function getWebDatetime() As StringDim XmlHttp As Object, objJs As Object, objStream As ObjectSet XmlHttp = CreateObject("Microsoft.XMLHTTP")XmlHttp.Open "GET", "http://api.k780.com:88/?app=life.time&appkey=10003&sign=b59bc3ef6191eb9f747dd4e83c99f2a4&format=json", FalseXmlHttp.SetRequestHeader "If-Modified-Since", "0"XmlHttp.sendSet objStream = CreateObject("Adodb.Stream")objStream.Type = 1objStream.Mode = 3objStream.OpenobjStream.Write XmlHttp.ResponseBodyobjStream.position = 0objStream.Type = 2objStream.Charset = "UTF-8"Set objJs = CreateObject("msscriptcontrol.scriptcontrol")objJs.Language = "jScript"getWebDatetime = objJs.eval("eval(" & objStream.ReadText & ").result.datetime_1")objStream.CloseSet objStream = NothingSet XmlHttp = NothingSet objJs = Nothing
End Function'方法三，读取网站服务器返回的时间，这里的百度网站可以换成任何其他的例如淘宝。强烈推荐
Private Function getWebDatetime() As StringDim XmlHttp As Object, objJs As ObjectSet XmlHttp = CreateObject("Microsoft.XMLHTTP")XmlHttp.Open "POST", "https://www.baidu.com", FalseXmlHttp.sendSet objJs = CreateObject("msscriptcontrol.scriptcontrol")objJs.Language = "jScript"getWebDatetime = objJs.Eval("var dt = new Date('" & XmlHttp.getResponseHeader("Date") & "');var date = [  [dt.getFullYear(), dt.getMonth() + 1, dt.getDate()].join('-'),  [dt.getHours(), dt.getMinutes(), dt.getSeconds()].join(':')].join(' ').replace(/(?=\b\d\b)/g, '0');date;")Set XmlHttp = NothingSet objJs = Nothing
End Function'方法四，直接用vb转换GMT时间（网友Chen8013提供），强烈推荐推荐
Private Function getWebDatetime() As StringDim XmlHttp As ObjectSet XmlHttp = CreateObject("Microsoft.XMLHTTP")XmlHttp.Open "POST", "https://www.baidu.com", FalseXmlHttp.sendgetWebDatetime = CDate(1 / 3 + CDbl(CDate(Mid$(XmlHttp.getResponseHeader("Date"), 5, 21))))Set XmlHttp = Nothing
End Function'方法五，来自https://blog.csdn.net/sitongqdl/article/details/46412633
Private Function GetTime() As DateDim oXMLHTTP As ObjectSet oXMLHTTP = CreateObject("MSXML2.XMLHTTP")oXMLHTTP.open "HEAD", "https://www.baidu.com", FalseoXMLHTTP.sendGetTime = DateAdd("h", 8,     CDate(Trim(Split(Split(oXMLHTTP.getResponseHeader("Date"), ",")(1), "GMT")(0))))
End Function

测试的时候注意删除掉另外两个函数，否则会发生同名函数冲突的问题。
