The ITimeZone interface provides read-only access to standard and daylight savings time zone information. You can create a time zone object by calling IPOutlookApp::GetTimeZoneFromIndex.

ITimeZone methods Description

ITimeZone::get_Bias

Gets the current bias, in minutes, for local time translation on this computer.

ITimeZone::get_SupportsDST

Determines whether a time zone supports daylight-saving time.

ITimeZone::get_IsStandardAbsoluteDate

Gets whether StandardDate is an absolute or relative date.

ITimeZone::get_IsDaylightAbsoluteDate

Determines whether DaylightDate is absolute or relative.

ITimeZone::get_StandardBias

Gets the offset in minutes added to a time zone when it is in standard time.

ITimeZone::get_StandardName

Gets the name of a time zone when standard time is in effect.

ITimeZone::get_StandardDate

Determines when a time zone enters standard time.

ITimeZone::get_StandardDayOfWeekMask

ITimeZone::get_DaylightInstance

Gets the week of the month (from one to five) daylight-saving time starts.

ITimeZone::get_DaylightMonthOfYear

Gets the month of the year daylight-saving time starts.

ITimeZone::get_Application

Gets the main Outlook Mobile IPOutlookApp object.

If a time zone does not support daylight-saving time (SupportsDST is FALSE), all subsequent values in the table are undefined.

The change between standard time and daylight-saving time is absolute if it falls on a particular date (such as April 5), and relative if it falls on a particular day (such as the first Sunday in April). The method used to find the times and dates of the changes depends on whether IsStandardAbsoluteDateandIsDaylightAbsoluteDate are TRUE or FALSE.

If IsStandardAbsoluteDate or IsDaylightAbsoluteDate is TRUE, then the date is absolute.

  • To find when a time zone changes from standard time to daylight-saving time, get DaylightDate and discard the year value.
  • To find when a time zone changes from daylight-saving time to standard time, get StandardDate and discard the year value.

If IsStandardAbsoluteDate or IsDaylightAbsoluteDate is FALSE, then the date is relative.
