Data insertion

Question

Hello,
my server is in germany.
I have to insert data into a table from two locations from Germany as well as from india.
But my intention is to insert the data with time zone GMT+2:00 at any point of time (whether i am inserting data from india or Germany)
All data should be inserted as per the german time even though data insertion is being done form india.
table name: data
Fields : id number, datatime timestamp with time zone, value number
could you please tell me how i should achieve it.
At present when i am inserting data from india it is going with GMT+5:30
And in germany as the daylightsaving is on. Two time zones will come up GMT+2:00, GMT+1:00
thanks in advance.
Kind Regards,
Mohan

Answer 1

thank for your reply.
you told me how to get the sessiontimezone.
but i am inserting the data as follows.
insert into data(id, datetime, value) values (1, to_date('20008-10-28 23:59:59', 'yyyy-mm-dd hh24:mi:ss', 1);
when i have run this stmt from my perl script(from my indian machine) it is inserting data with time zone +5:30
when i have run the same script on the german server it is inserting data with GMt+2:00.
But my intension is as follows.
Indian machine : insert into data(id, datetime, value) values (1, to_date('20008-10-28 23:59:59', 'yyyy-mm-dd hh24:mi:ss', 1);
select * from data where id = 1;
1, 20008-10-28 23:59:59.000000 GMT+5:30, 1
Indian machine: insert into data(id, datetime, value) values (2, to_date('20008-10-28 23:59:59', 'yyyy-mm-dd hh24:mi:ss', 2);
select * from data where id = 2;
2, 20008-10-28 23:59:59.000000 GMT+2:00, 2
my intension is first one also should be inserted as 20008-10-28 23:59:59.000000 GMT+2:00.
Please let me know if you did not get what i am asking.

Mohan
