leading zeros ignored by perl, ksh. not bash

[Maik.Liedtke]

hello,

to change our scripts from ksh to bash we have problems with vars and leading 
zeros.
how we can declare hrs and min?
or can we disable the automatic change from decimal to octal?


leading zeros ignored by perl, ksh. not bash
cannnot declare vars hrs and min as decimal only


user@host:/home/user> ./mltest.pl
TIME = 08:09
hrs=08 | min=09 | locmin=489


user@host:/home/user> ./mltest.ksh
TIME=08:09
hrs=8 | min=9 | locmin=489


user@host:/home/user> ./mltest.sh
TIME=08:09
./mltest.sh: line 9: 08: value too great for base (error token is "08")
./mltest.sh: line 10: 09: value too great for base (error token is "09")
hrs= | min= | locmin=0


code (mltest.sh)

#!/bin/bash

declare -i hrs min locmin

TIME="08:09"
echo "TIME=$TIME"

hrs=$(echo ${TIME}|cut -f1 -d ':')
min=$(echo ${TIME}|cut -f2 -d ':')
#hrs=$(echo ${TIME}|cut -f1 -d ':'|bc -l)             # workaround 1: ok
#min=$(echo ${TIME}|cut -f2 -d ':'|bc -l)             # workaround 1: ok
###hrs=$(echo ${TIME}|cut -f1 -d ':'|sed "s/^0*//")   # workaround 2: ok
###min=$(echo ${TIME}|cut -f2 -d ':'|sed "s/^0*//")   # workaround 2: ok

locmin=hrs*60+min

echo "hrs=$hrs | min=$min | locmin=$locmin"
