Eclipse overwrites these files when we import projects using m2e.
Eclipse 3 writes a timestamp at the top of these files making the Git
working tree dirty. Eclipse 4 (Juno) still overwrites these files but
doesn't write the timestamp. This should help keeping the working tree
clean. However, since the timestamp is currently present in these
files, Eclispe 4 would still make them dirty by overwriting and
effectively removing the timestamp.
This change removes the timestamp from these files. This help those
using Eclipse 4 and doesn't make it worse for those still using Eclispe
3.
