Attributes Tab

The Attributes tab is an object type-specific tab which is only available within the "TimeZone" object. The values used for conversion from UTC (Coordinated Universal Time), the standard AE time, into local time are set in this tab.

Object: TimeZone
Object class: System object
Object type (short name): TZ

TimeZone objects can also store different specifications for individual years. This function has been added in order to facilitate the integration of date modifications. The USA, for example, will use a different date for changing from Daylight Savings Time to normal time as of 2007.

It is also possible to adjust a TimeZone object in the year in which the date will be changed. In doing so, the object's statistical records of previous years would be affected as they would show wrong values because they use the new specifications made for the TimeZone object.

Follow the steps described below to configure your TimeZone object:

Open the TimeZone object
Pay attention to the field Year . It refers to the year from which onwards the TimeZone specifications will apply. Enter the starting year for the new values for changing from Daylight Savings Time to normal time.
Specify new settings in the rest of the tab
Store the TimeZone object

AE internally stores the old specification and creates a new data record for the new specification. For new calculations with the year being < than the new definition, the data record for the particular year is searched for and used for calculations from UTC to local time.

Just enter the year if you intend to change a TimeZone specification. The modified settings are then stored for this particular year.

View: Only the specifications made for the latest year are displayed, all other specifications are available in the background but are not displayed.

Please note: You may only use calendar systems that are based on the Gregorian calendar.
