How to convert “1985-02-07T00:00:00.000Z” (ISO8601) to a date value in Oracle?

Question

I tried to convert a time-stamp (\"1985-02-07T00:00:00.000Z\") to a date and I failed to succeed in my several different attempts.

Below is the query I have tried:

Answer 1

SELECT to_timestamp_tz('2012-08-08T09:06:14.000-07:00','YYYY-MM-DD"T"HH24:MI:SS.FF3TZR')
FROM dual;

External table DDL,
extract_date char(29) DATE_FORMAT timestamp WITH TIMEZONE mask 'YYYY-MM-DD"T"HH24:MI:SS.FF3TZR'
