part of the puzzle: the GNU date time understands the Unix 'epoch' time.
see man date; and info date

e.g.
   $ date --date=@1168396306
   Wed Jan 10 13:31:46 EST 2007
   $ date --date=@791585666
   Wed Feb  1 07:54:26 EST 1995
   $ echo $(( 1168396306 + 791585666 ))
   1959981972
   $ date --date=@1959981972
