That range isn't part of GNU date, I don't think. Under OS X, I get a different result.
For the negative bound:

pb3:xj2 jhawk$ gdate --version
date (GNU coreutils) 8.30
pb3:xj2 jhawk$ gdate -d @-67768040609722801
gdate: time ‘-67768040609722801’ is out of range
pb3:xj2 jhawk$ gdate -d @-67768040609722800
Thu Jan  1 00:00:00 EST -2147481748
pb3:xj2 jhawk$ 

Not that this matters critically.
