I don't know why it doesn't work (I know pretty little about shell
programming), but the following does work (for me, anyway):
#!/bin/sh
echo '#!/bin/sh
NOWS=$(date +%S)
NOWS=${NOWS#0}
NOWM=$(date +%M)
NOWM=${NOWM#0}
NOWH=$(date +%H)
NOWH=${NOWH#0}
FROMNOW=$1
MINUTE=$((${NOWM} + ${FROMNOW}))
MINUTE=$((${MINUTE} % 60))
HOUR=$((${NOWM} + ${FROMNOW}))
HOUR=$((${HOUR} / 60))
HOUR=$((${NOWH} + ${HOUR}))
HOUR=$((${HOUR} % 24))
echo $HOUR" "$MINUTE' >newscriptfile.sh
