时间问题

时间一致性

// 把美国东部标准时间转换成本低时间
DateTime source= DateTime.SpecifyKind(USEasternStandardTime,DateTimeKind.Unspecified);
DateTime utcTime = TimeZoneInfo.ConvertTimeToUtc(source, TimeZoneInfo.FindSystemTimeZoneById("US Eastern Standard Time"));
result = TimeZoneInfo.ConvertTimeFromUtc(utcTime, TimeZoneInfo.Local);

var lst = TimeZoneInfo.GetSystemTimeZones();
foreach (TimeZoneInfo tzi in lst)
{
Console.WriteLine(tzi.Id);
}
