I have a ISO-8601 date in VARCHAR2 type, how can i convert that String date to timestamp in oracle db?
Date Example: "2014-09-12T11:53:06+00:00"
Maybe is something like the following but i not sure what is the format.
SELECT to_timestamp_tz ('2014-09-12T11:53:06+00:00', ????) FROM DUAL

The date format model elements are listed in the Datetime Format Models documentation:
SELECT to_timestamp_tz ('2014-09-12T11:53:06+00:00', 'YYYY-MM-DD"T"HH24:MI:SSTZH:TZM')
FROM DUAL
TO_TIMESTAMP_TZ('2014-09-12T11:53:06+00:00','YYYY-MM-DD"T"HH24:MI:SSTZH:TZM')

12-SEP-14 11.53.06.000000000 +00:00
The fixed T can be included as a character literal:
You can include these characters in a date format model:
- Punctuation such as hyphens, slashes, commas, periods, and colons
- Character literals, enclosed in double quotation marks
TZH is tome zone hour, and TZM is time zone minutes. The rest are more common model elements.
