Date field problem - is this a bug?

[h33]

I want to add a full stop to the end of my date field, so i use this code:

=[Return Date] & "."

It adds the "." but it changes the format of the date to 'General Date'. I want it to be long date. If I take the "." out of the field, it reverts to long date.

Is there a work around?
