Asp.net中的时区
首先，日期時間轉換在 Asp.net 中的幾種應用：
1.?<ASP:BOUNDCOLUMN DATAFIELD= "JoinTime " DATAFORMATSTRING= "{0:yyyy-MM-dd} " >??? <ITEMSTYLE WIDTH= "18% "?? >?? </ITEMSTYLE >?? </ASP:BOUNDCOLUMN >?
2.?? e.Item.Cell[0].Text = Convert.ToDateTime(e.Item.Cell[0].Text).ToShortDateString();?
3.?? String.Format( "yyyy-MM-dd ",yourDateTime);???????
4.?? Convert.ToDateTime("2005-8-23").ToString("yyMMdd",System.Globalization.DateTimeFormatInfo.InvariantInfo);???
5.?? <asp:BoundColumn DataField="收款時間" HeaderText="收款時間"?
DataFormatString="{0:yyyy-mm-dd}">?? </asp:BoundColumn>?
6.?? DateTime.Now.ToString("yyyyMMddhhmmss")?
7.?? DateTime.Now.ToString("yyyy/MM/dd hh:mm:ss")?
8.?? 只顯示年月?
DataBinder.Eval(Container.DataItem,"starttime","{0:yyyy-M}")?
9.??? <asp:BoundColumn DataField="收款時間" HeaderText="收款時間"?
DataFormatString="{0:yyyy-MM-dd HH24:mm:ss}">??? </asp:BoundColumn>??
?
其次，系統中有效時區列表：
1. 根據本地時間取得時區列表：
??????? DateTimeOffset chinaDate = DateTimeOffset.Now; //本地當前時間
??????? Response.Write(chinaDate.ToString() + "<br/>");
??????? ReadOnlyCollection<TimeZoneInfo> zones = TimeZoneInfo.GetSystemTimeZones();//系統中地時區標識列表
??????? foreach (TimeZoneInfo timeZoneInfo in zones)
??????? {
??????????? //通過本地時間取得格林威治標準時間，并通過這個標準時間取得不同時區ID的名稱及它的相應時間
??????????? DateTimeOffset easternDate = TimeZoneInfo.ConvertTime(chinaDate.UtcDateTime,
??????????????? TimeZoneInfo.FindSystemTimeZoneById(timeZoneInfo.Id));
??????????? Response.Write(timeZoneInfo.Id + ": "?
??????????????? + easternDate.ToString() + "<br/>");
??????? }
???????所得結果如下：

其次，取得客戶端時區偏移量（javascript）：
??? var zone = new Date().getTimezoneOffset()/60 * -1;
?
最后，取得在客戶端應正確顯示的時間：
??????????? //serverZoneID 為數據庫所在時區的ID，例如上面列表中的：“Eastern Standard Time”
??????????? DateTimeOffset serverDateTime = TimeZoneInfo.ConvertTime(
??????????? databaseDateTime, TimeZoneInfo.FindSystemTimeZoneById(serverZoneID));
??????????? //zone 表示客戶端時區偏移量
??????????? serverDateTime.UtcDateTime.AddHours(zone);
