Date value mismatch btw delimited file and source table

Hello,
 
I am using TPT to export data from a Teradata table to delimited file.
Below is the script:

APPLY TO OPERATOR (FILE_WRITER) 

SELECT * FROM OPERATOR (SQL_SELECTOR); );

------------------------------

My issue is for the date column export where the data value extracted is not a date value at all.

Source value: "2012-10-23 10:01:51"

Value in file: "1:51-10-23 10:01:51"

I have 3 date clolumn in the query and the issue varies from one run to other. I hav not got a single stagnent issue with a date value, it varies on every run (row and column). with use of where clause to limit the number of records, the data looks fine. 

But for the xtract of full table, in this requiremnet of 22 Gigs, I am unable to get desired data set in the file.

Appreciate your suggestion.

Thanks,

Rahul Verma
