Probably me being thick but....

Have a sheet of data, one field it date/time (dd/mm/yyyy hh:nn:ss).
Copied the data from Access. Pasted into Excel

The date I have visible is : 19/01/2009 18:59:00
Note the extra space in between the time and date. I removed it - Excel put it back.
Year coming out in another cell is : 1905


Please tell me its something I'm doing wrong...
