Sort the date in database column of sqlite

I am making an iPhone app. In this app i am using sqlite database for storing the dates in the column.

The date which I am storing in the database column is not in the sorting order as you can see in the image. Now I want to sort the date according to ascending order. How can I do this. Please provide me so开发者_JAVA技巧me solution.

You need to store the datetime in timestamp format and then try to sort them.
