| [ in]operand | A Variantof typeString, a numeric value, or anOraIntervalDSobject to be added. | 
The result of the operation is stored in an OraIntervalDS object, overwriting any previous value. There is no return value.
If operand is a Variant of type String, it must be in the following format: [+/-]Day HH:MI:SSxFF.
If operand is a numeric value, the value provided should represent the total number of days that the constructed OraIntervalDS object represents.
Dim oraIDS as OraIntervalDS 
 
'Create an OraIntervalDS using a string which represents 
'1 day and 12 hours 
Set oraIDS = oo4oSession.CreateOraIntervalDS("1 12:0:0.0") 
 
'Add an interval using a string, which represents 2 days 
'and 12 hours, to oraIDS. 
'The resulting oraIDS is an interval which represents 4 days  
oraIDS.Add "2 12:0:0.0"
