Hello karnan sekar,
The only way I could come up with is the following:
1. It is too late to format the dates in the Grid (in list view), since the dates come as plain values.
2. We had to format the dates at earlier stage, so they appear in the same format everywhere.
You can add a new metafield for the Created field, and hide the default field. In your custom metafield you could enter the date in any format (or format it automatically on save). Adding a custom MetaField is described in the User Manual.
I hope this helps.
