在C#中, 将不同时区DateTime,转换成当前用户的时间?

请参考帮助文档：http://msdn.microsoft.com/zh-cn/library/bb397769(v=VS.90).aspx
首先你应该是知道你这个要存入的时区是哪里的吧？
各个时区标识符参照列表链接：http://msdn.microsoft.com/zh-cn/library/bb384272(v=VS.90).aspx
首先将指定时区转为UTC(协调世界时)时间，再把UTC转为本地时间
DateTime easternTime = new DateTime(2007, 01, 02, 12, 16, 00);
string easternZoneId = "Eastern Standard Time";
TimeZoneInfo easternZone = null;
DateTime utcTime = DateTime.UtcNow;
try
{
easternZone = TimeZoneInfo.FindSystemTimeZoneById(easternZoneId);
utcTime = TimeZoneInfo.ConvertTimeToUtc(easternTime, easternZone);
}
catch (TimeZoneNotFoundException)
{
Console.WriteLine("Unable to find the {0} zone in the registry.", easternZoneId);
}
catch (InvalidTimeZoneException)
{
Console.WriteLine("Registry data on the {0} zone has been corrupted.", easternZoneId);
}
DateTime dtLocal = utcTime.ToLocalTime(); //将UTC时间转为本地时间
