libxml version on my machine gives wrong values for non-existent attributes (It gives "http://schemas.openxmlformats.org/spreadsheetml/2006/main").
I had to change node.attribute('t') to node.attributes['t'] so cell_type would be nil if 't' attribute doesn't exists.
This fixes my problem of dates not being parsed correctly.

Solution: 
	change all access to attributes to use .attributes[..] syntax
