Even if you find one, remember that such a command would be internally converting to seconds-since-epoch and then doing the arithmetic. > figure is not constant. One way out is that every day the %s figure is > generated at exactly 10:00 and this is then 'diff'ed with the user's > attendance time in %s. This is then divided by 60. You don't need to do that. You can simply do: late=$(( `date '+%s'` - `date '+%s' -d 'today 10am'` )) And then convert $late to any format you want. Binand -- http://mm.glug-bom.org/mailman/listinfo/linuxers
