having problem with timepatch

[Guest]

Guys I am completely confused with this timezone patch.

I have added it

now when I add products (in categories) it says this :

 

1064 - You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near 'date_add(now(), INTERVAL -h,4 HOUR) where products_id = '1579''

 

update products set products_quantity = '50', products_model = '0340220016', products_price = '49.9500', products_date_available = null, products_weight = '0.00', products_status = '1', products_tax_class_id = '1', manufacturers_id = '', products_image = 'test.jpg', date_add(now(), INTERVAL -h,4 HOUR) where products_id = '1579'

 

[TEP STOP]

 

what is the problem with my sql? and how do i fix it

 

look forward to your reply
