How to change date format on Timeline?

The timeline date format currently reads as 13.03.2013. I would like to change this to 13 March 2013 instead. Where can I change this? Thanks

Still curious which file I need to edit for this if anyone knows.

You use to be able to set the date format but I can not seem to find it.  I looked in every conceivable place in the backend.

admin - settings - language settings - settings

EDIT - thats on 7.1.3

Yes, I remember now.  There is a topic on this somewhere in which I participated LOL.  

I would like to do the same with the month spelled out instead of just numeric. How does one change "d.m.Y" to reflect the alpha characters in addition to the numeric?

That is a part of php date().  Go to http://php.net/manual/en/function.date.php and you will get the full list of how to format the output.

That was an easy fix - Thanks for the info! Also appreciate the link, that site looks like a storehouse of knowledge. Bookmarked and I'm sure that I will be visiting often.
