Possible Defect with Crystal and date formating

Question

Crystal 2008 Oracle 11.1
I am building functionality to override dates within my Crystal/SP by passing a String as a IN/OUT Parameter from Crystal.
I have 2 Functions in use that have been tested. The first parses the string and returns a number of database parameters with any overrides passed in the string. The second is a date function that will return a Start date and calculate the End date based on a Frequency Parameter value passed from the first function. (Daily, Monthly,Quarterly) or pass the END date from the string back.
We are using the Default Oracle Date format of dd-MON-yy (22-SEP-10)
I am casting my string using the ORACLE To_Date(parsed String value) function and loading it into the array of DATE types that I am passing to the driver SP. In here I am moving the occurane of my array to a LV_Sdate and LV_Edate fields that are defined as DATE.
Data
Oracle Dates  copied from the Oracle Table -
CURR_DT - 23-SEP-10    PREV_DT- 21-SEP-10     OLD_DT - 20-SEP-10
Using Table Date - PREV_DT Calculating END by Moving Date to Second Array Position returns:
  PRFL_NB_TX       CO_NM               CNTC_NM                        Start Date                 End Date
  xxxxxxxx        XXXX-ACADEMY           ROB TESTNAME       9/21/2010  12:00:0  9/21/2010  12:00:0
Using Passed Dates Both Start and End  --- OVERRIDE String: 1@1$620360008@BEGDATE$25-SEP-10@ENDDATE$25-SEP-10@
  PRFL_NB_TX       CO_NM                  CNTC_NM                          Start Date                 End Date
  xxxxxxxx        XXXX-ACADEMY           ROB TESTNAME        9/10/25  12:00:00A  9/10/25  12:00:00A
Using Table and Passed Dates Start - Table, End - Passed  -
OVERRIDE String: 1@1$620360008@ENDDATE$29-SEP-10@
  PRFL_NB_TX       CO_NM                  CNTC_NM                          Start Date                 End Date
  xxxxxxxx        XXXX-ACADEMY           ROB TESTNAME        9/21/2010  12:00:0  9/10/29  12:00:00A
Notice the Start and END date YEAR
Here is where things get a bit confusing as the functions called either read the Database or format the date and Return it in the same DATE array.
The data provided above was exported as a txt file from a basic Crystal report.
I can provide Code snipits if needed including native SQLDeveloper exection displays where the date returned to the SP is correct

Answer 1

This was a date CAST issue in one formula. I had cast all the others in the function and the one missing one was causing the issues.
Thanks for all who read.
