TimezoneDSTOffsetFrom Property

The UTC offset that is in use when the onset of this time zone observance begins.

Syntax

 caldav.getTimezoneDSTOffsetFrom([callback])
 caldav.setTimezoneDSTOffsetFrom( timezoneDSTOffsetFrom, [callback])

Default Value

""

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for the getTimezoneDSTOffsetFrom([callback]) method is defined as:

function(err, data){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'data' is the value returned by the method.

The callback for the setTimezoneDSTOffsetFrom([callback]) method is defined as:

function(err){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

The UTC offset that is in use when the onset of this time zone observance begins. TimezoneDSTOffsetFrom is combined with TimezoneDSTStart to define the effective onset for the daylight-time time zone definition.

TimezoneDSTStart, TimezoneDSTOffsetFrom, and TimezoneDSTOffsetTo are all required to specify the daylight-savings time zone.

The following example shows the CalTimezone set to Eastern time.

  CalDAV.Timezone.TimezoneId      = "US-Eastern";
  CalDAV.Timezone.URL             = "http://zones.example.com/tz/America-New_York.ics"

  CalDAV.Timezone.StdName         = "Eastern Standard Time (US & Canada)";
  CalDAV.Timezone.StdStart        = "20071104T020000";
  CalDAV.Timezone.StdOffsetFrom   = "-400";
  CalDAV.Timezone.StdOffsetTo     = "-500";
  CalDAV.Timezone.StdRule         = "FREQ=YEARLY;BYDAY=1SU;BYMONTH=11";

  CalDAV.TimeZone.DSTName         = "Eastern Daylight Time (US & Canada)";
  CalDAV.TimeZone.DSTStart        = "20070311T020000";  
  CalDAV.TimeZone.DSTOffsetFrom   = "-500";
  CalDAV.TimeZone.DSTOffsetTo     = "-400";
  CalDAV.TimeZone.DSTRule         = "FREQ=YEARLY;BYDAY=2SU;BYMONTH=3";
