You can use a pattern expansion:
Code:
a=$(( ( a * 60) + ${x#0} ))
Or just a better way of doing what I'm doing =)
No forks, and unrolling the loop for simplicity:

Code:
IN=00:08:19.12
IFS=: read h m s <<EOF
${IN%%.*}
EOF

a=$(( ${h#0} * 3600 + ${m#0} * 60 + ${s#0} ))
Quick'n'dirty hack (ab)using date:

Code:
date -u -d 1970.01.01-${IN%%.*} +%s
(Note: the input date format is highly non-portable)
