Please use [ code ][ /code ] (sans the space) for code/logs/listings/...
Code:
$ TIME=$( date +%s )
$ LANG=C date -ud @`echo $TIME`
Fri Mar 13 14:37:15 UTC 2009
$ SEC=$(( ${TIME} % 60 ))
$ MIN=$(( ${TIME} % 3600 / 60 ))
$ HR=$(( ${TIME} % (3600*24) / 3600 ))
$ echo $HR $MIN $SEC
14 37 15
$
$
$ SIZE=$(( 200*1024*1024 ))
$ KB=$(( ${SIZE} / 1024 ))
$ MB=$(( ${SIZE} / 1024 / 1024 ))
$ GB=$(( ${SIZE} / 1024 / 1024 / 1024 ))
$ BITS=$(( ${SIZE} * 8 ))
$ echo $GB $MB $KB $SIZE $BITS
0 200 204800 209715200 1677721600
$

This code worked both on Linux/HP-UX using bash/ksh on both (except for the second date call, HP-UX' date doesn't like the -d switch). As for the Base-16 to Base-10 conversion, it's probably easier to do that in Perl than to code in in the shell.
