Question

I\'m facing an issue while converting dates between my server and client where both is running in Germany. The Regional settings on the client machines could be set to both

Answer 1

Use TimeZoneInfo.ConvertTime to convert original input timezone (CET) to target timezone (UK).

public static DateTime ConvertTime(
    DateTime dateTime,
    TimeZoneInfo sourceTimeZone,
    TimeZoneInfo destinationTimeZone
)

Full guidance on MSDN here:

Converting Times Between Time Zones

Modified code sample from MSDN:

DateTime ceTime = new DateTime(2007, 02, 01, 08, 00, 00);
try
{
   TimeZoneInfo ceZone = TimeZoneInfo.FindSystemTimeZoneById("Central Europe Standard        Time");
   TimeZoneInfo gmtZone = TimeZoneInfo.FindSystemTimeZoneById("GMT Standard Time");
   Console.WriteLine("{0} {1} is {2} GMT time.", 
           ceTime, 
           ceZone.IsDaylightSavingTime(ceTime) ? ceZone.DaylightName : ceZone.StandardName, 
           TimeZoneInfo.ConvertTime(ceTime, ceZone, gmtZone));
}
catch (TimeZoneNotFoundException)
{
   Console.WriteLine("The registry does not define the required timezones.");
}                           
catch (InvalidTimeZoneException)
{
   Console.WriteLine("Registry data on the required timezones has been corrupted.");
}
