  • 本地时间与格林威治时间相互转换

    public static DateTime LocalTime2GreenwishTime(DateTime lacalTime)
            {
                TimeZone localTimeZone = System.TimeZone.CurrentTimeZone;
                TimeSpan timeSpan = localTimeZone.GetUtcOffset(lacalTime);
                DateTime greenwishTime = lacalTime - timeSpan;
                return greenwishTime;
            }

    public static DateTime GreenwishTime2LocalTime(DateTime greenwishTime)
            {
                TimeZone localTimeZone = System.TimeZone.CurrentTimeZone;
                TimeSpan timeSpan = localTimeZone.GetUtcOffset(greenwishTime);
                DateTime lacalTime = greenwishTime + timeSpan;
                return lacalTime;
            }

    PS:关于非DateTime类型的字符串格式的转换

    string strDate ="Mon Aug 15 2011 00:00:00 GMT+0800";

    DateTime date = DateTime.ParseExact(strDate, @"ddd MMM dd yyyy HH:mm:ss GMT+ffff", CultureInfo.CreateSpecificCulture("en-US"));

    Response.Write(date.ToString());

     

    string str="Tue Jun 11 09:30:00 UTC 0800 2013";

    DateTime dt=DateTime.ParseExact(str,"ddd MMM dd HH:mm:ss 'UTC' 0800 yyyy", System.Globalization.CultureInfo.InvariantCulture);

    Response.Write(date.ToString());
