Question: We receive a file from an external provider. One of the columns contains a timestamp in the form "05/01/2014 09:25:41 AM EDT". I am trying to insert this into a TIMESTAMP WITH TIME ZONE column with the following SQL:

`INSERT INTO table VALUES (to_timestamp_tz('05/01/2014 09:25:41 AM EDT', 'MM/DD/YYYY HH12:MI:SS AM TZR TZD'));`

That is when I get `ORA-1882: timezone region not found`. I've also tried specifying this like

`INSERT INTO table VALUES (to_timestamp_tz('05/01/2014 09:25:41 AM EST EDT', 'MM/DD/YYYY HH12:MI:SS AM TZR TZD'));`

but then I get `ORA-1857: not a valid time zone`.

Anyone have an idea how I can insert this? We are running Oracle 11.2.0.3. I can see in `v$timezone_names` that EST and EDT both appear to be valid tzabbrev for tzname 'America/New York'.

EDIT:

It appears that if I substitute EST5EDT for EDT (and CST6CDT, MST7MDT, and PST8PDT for CST, MST, and PST, respectively) , I can get the behavior I need. The problem with this is that I need to know what these substitutions are in advance so I can code around them. I still need to know how to handle potential daylight savings time issues with other timezones.

Answer: 
* Server-sided: Runs on server (like Node.js)
* Client-sided: Runs in browser
* Core: The set of functionality available to all javascript engines
after installation of node js in system then we use javascript on server side. the code of nodejs is just like a javascript. no major differences so its also a javascript. Nodejs enables the user to use javascript code on server side too.
