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";
