Sheesh, why cannot they just give a simple formula so I could convert the values on another column in Excel to get the human time/date

simple:
assume A1 contains that funky number:
paste '
=A1/86400+"1/1/70"' into B1 and format the cell for date/time..

thus: 1183780091 becomes 7/7/07 3:48 AM
*poof* done
