For the footprint itself ( i.e. when inside a library, not inside a 
board), the time stamp is not used.
It is actually used only when loaded on a board, and it is modified when 
reading a netlist.
Therefore the time stamp of the footprint itself, if exists, will be 
replaced the first time a netlist is read.
