Better to use quotes:

#! /bin/sh
# cat logfile | viewlog.sh              -> 2000-07-05 08:37:33
# cat logfile | viewlog.sh 2            -> 2000-07-05 08:37:33.21
# cat logfile | viewlog.sh 9 or greater -> 2000-07-05 08:37:33.213730500

if [ $# = 0  -o "$1" = "0" ]; then
    tai64nlocal | awk  '{ $2 = substr($2,1,8); print }'
elif [ "$1" -gt "0" -a "$1" -lt "9" ]; then
    tai64nlocal | awk  '{ $2 = substr($2,1,'`expr $1 + 9`'); print }'
else
    tai64nlocal
fi
