standardDisplayName - The new time zone's standard time name.
daylightDisplayName - The daylight saving time name of the new time zone.
adjustmentRules - An array that augments the base UTC offset for a particular period.

Returns

TimeZoneInfo.CreateCustomTimeZone(String, TimeSpan, String, String, String, TimeZoneInfo.AdjustmentRule[]) method returns A TimeZoneInfo object that represents the new time zone.

Example

The following example creates a custom time zone.


/* ww  w.  ja  va 2  s.  c om*/
using System;
public class MainClass{
  public static void Main(String[] argv){  
    TimeZoneInfo.TransitionTime startTransition, endTransition;
    startTransition = TimeZoneInfo.TransitionTime.CreateFloatingDateRule(new DateTime(1, 1, 1, 4, 0, 0), 
                                                                      10, 2, DayOfWeek.Sunday); 
    endTransition = TimeZoneInfo.TransitionTime.CreateFloatingDateRule(new DateTime(1, 1, 1, 3, 0, 0), 
                                                                    3, 2, DayOfWeek.Sunday);
    // Define adjustment rule
    TimeSpan delta = new TimeSpan(1, 0, 0);
    TimeZoneInfo.AdjustmentRule adjustment;
    adjustment = TimeZoneInfo.AdjustmentRule.CreateAdjustmentRule(new DateTime(1999, 10, 1), DateTime.MaxValue.Date, delta, startTransition, endTransition);
    
    TimeZoneInfo.AdjustmentRule[] adjustments = {adjustment};
    
    string displayName = "(GMT-04:00) Custom Time";
    string standardName = "Palmer Time";
    string daylightName = "Palmer Daylight Time";
    TimeSpan offset = new TimeSpan(-4, 0, 0);
    TimeZoneInfo palmer = TimeZoneInfo.CreateCustomTimeZone(standardName, offset, displayName, standardName, daylightName, adjustments);
    Console.WriteLine("The current time is {0} {1}",  
                      TimeZoneInfo.ConvertTime(DateTime.Now, TimeZoneInfo.Local, palmer), 
                      palmer.StandardName);

  }
}

The code above generates the following result.
