Extracting date from a series of numbers

Hello,

I need to extract "date" exsiting in a specific space in a series of numbers and get it in another cell. I don't want to split the series using 'text to column" and then pick up the date.

Example:

Data (Column A)
20100103001
20100203555
20100304668
20100201365
20100201568

Where: space 1 to 4 indicate year, space 5 to 6 indicate month, space 7 to 8 indicate date and space 9 to 12 is any sequence number and doesn't needed in Answer column B and is ignoreable.

The Required Column B should be as follow:

Column B
03-Jan-2010
03-Feb-2010
04-Mar-2010
01-Feb-2010
01-Feb-2010

Thanks......seekermay
