'Usage
 
Dim dateStart As System.Date
Dim dateEnd As System.Date
Dim daylightDelta As System.TimeSpan
Dim daylightTransitionStart As NTransitionTime
Dim daylightTransitionEnd As NTransitionTime
Dim value As NAdjustmentRule
 
value = NAdjustmentRule.CreateAdjustmentRule(dateStart, dateEnd, daylightDelta, daylightTransitionStart, daylightTransitionEnd)

public static NAdjustmentRule CreateAdjustmentRule( 
   System.DateTime dateStart,
   System.DateTime dateEnd,
   System.TimeSpan daylightDelta,
   NTransitionTime daylightTransitionStart,
   NTransitionTime daylightTransitionEnd
)

Parameters

dateStart

The effective date of the adjustment rule. If the value of the dateStart parameter is DateTime.MinValue.Date, this is the first adjustment rule in effect for a time zone.

dateEnd

The last date that the adjustment rule is in force. If the value of the dateEnd parameter is DateTime.MaxValue.Date, the adjustment rule has no end date.

daylightDelta

The time change that results from the adjustment. This value is added to the time zone's NTimeZoneInfo.BaseUtcOffset property to obtain the correct daylight offset from Coordinated Universal Time (UTC). This value can range from -14 to 14.

daylightTransitionStart

A NTimeZoneInfo.TransitionTime object that defines the start of daylight saving time.

daylightTransitionEnd

A NTimeZoneInfo.TransitionTime object that defines the end of daylight saving time.
