added back order list time when less than 24 hours

So back in 2.0.20 we had this feature of order list showing the time when the order is less than 24 hours old.  This was a great feature and I am not too sure why this was taken out after 2.1.  I have looked through the history and did not find where/why it was changed.

But just in case it was taken out by accident, this PR puts it back in.
