C# TimeZoneInfo CreateCustomTimeZone(String, TimeSpan, String, String, String, TimeZoneInfo.AdjustmentRule[], Boolean)

Description

TimeZoneInfo CreateCustomTimeZone(String, TimeSpan, String, String, String, TimeZoneInfo.AdjustmentRule[], Boolean) creates a custom time zone with a specified identifier, an offset from Coordinated Universal Time (UTC), a display name, a standard time name, a daylight saving time name, daylight saving time rules, and a value that indicates whether the returned object reflects daylight saving time information.

Syntax

TimeZoneInfo.CreateCustomTimeZone(String, TimeSpan, String, String, String, TimeZoneInfo.AdjustmentRule[], Boolean) has the following syntax.

public static TimeZoneInfo CreateCustomTimeZone(
  string id,/*from  w ww  . j  a v a 2s  .  c o m*/
  TimeSpan baseUtcOffset,
  string displayName,
  string standardDisplayName,
  string daylightDisplayName,
  TimeZoneInfo.AdjustmentRule[] adjustmentRules,
  bool disableDaylightSavingTime
)

Parameters

TimeZoneInfo.CreateCustomTimeZone(String, TimeSpan, String, String, String, TimeZoneInfo.AdjustmentRule[], Boolean) has the following parameters.

• id - The time zone's identifier.
• baseUtcOffset - A TimeSpan object that represents the time difference between this time zone and Coordinated Universal Time (UTC).
• displayName - The display name of the new time zone.
• standardDisplayName - The standard time name of the new time zone.
• daylightDisplayName - The daylight saving time name of the new time zone.
• adjustmentRules - An array of TimeZoneInfo.AdjustmentRule objects that augment the base UTC offset for a particular period.
• disableDaylightSavingTime - true to discard any daylight saving time-related information present in adjustmentRules with the new object; otherwise, false.

Returns

TimeZoneInfo.CreateCustomTimeZone(String, TimeSpan, String, String, String, TimeZoneInfo.AdjustmentRule[], Boolean) method returns The new time zone. If the disableDaylightSavingTime parameter is true, the returned object has no daylight saving time data.

Example

The following example creates a custom time zone.

/* w w  w.  j  ava2s.c o  m*/
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 = TimeZoneInfo.AdjustmentRule.CreateAdjustmentRule(new DateTime(1999, 10, 1), 
                                          DateTime.MaxValue.Date, delta, startTransition, endTransition);
    
    TimeZoneInfo.AdjustmentRule[] adjustments = {adjustment};
    // Define other custom time zone arguments 
    string displayName = "(GMT-04:00) myTimeZone Time";
    string standardName = "myTimeZone Standard Time";
    string daylightName = "myTimeZone Daylight Time";
    TimeSpan offset = new TimeSpan(-4, 0, 0);
    
    TimeZoneInfo myTimeZone = TimeZoneInfo.CreateCustomTimeZone(standardName, offset, displayName, standardName, 
                                                      daylightName, adjustments, true);
    
    
    Console.WriteLine(myTimeZone.StandardName);
    Console.WriteLine(myTimeZone.SupportsDaylightSavingTime);

  }
}
    

The code above generates the following result.
