DateTime.Now doesn't respond to time zone changes

I built a clock using DateTime.Now and receive a time zone from a server. The problem is that the DateTime keeps using the old time zone.

(I want it to start using the new time zone set when I receive without having to reboot)

How do I get around this problem?

You have to Clear the Time Cash after changing Time. Use the following Command:

TimeZoneInfo.ClearCachedData()

You need to convert the current local time into the desired timezone. Something like this:

var timeInServerTimezone = TimeZoneInfo.ConvertTime(DateTime.Now, timeZoneInfoReceivedFromServer);

Have you tried using the TimeZone class instead of DateTime? I am not sure if it will make a difference but worth taking a look.

 DateTime baseUTC = new DateTime( 2000, 1, 1 );
 TimeZone localZone = TimeZone.CurrentTimeZone;
 DateTime localTime = localZone.ToLocalTime( baseUTC );
