you seem to have missed 1 field
the correct format should be
Code:
YYYY:MM:DD:HH:mm:ss

or you wanted this only?

---------- Post updated at 03:36 PM ---------- Previous update was at 03:05 PM ----------

Try:
Since you wanted the diff in sec, I have left it in sec.
for the condition when the years are diff, you will have to add the condition.
Code:
#!/bin/bash

timeCalc()
{
   (( _diff = ($1*3600+$2*60+$3) - ($4*3600+$5*60+$6) ))
   return ${_diff}
}

date1=2009:07:15:12:36
date2=2009:07:15:12:16

echo $date1
echo $date2

_date1=$(echo $date1|awk -F":" '{print $1" "$2" "$3}')
_date2=$(echo $date2|awk -F":" '{print $1" "$2" "$3}')
_time1=$(echo $date1|awk -F":" '{$6==""?$6=0:$6=$6;print $4" "$5" "$6}')
_time2=$(echo $date2|awk -F":" '{$6==""?$6=0:$6=$6;print $4" "$5" "$6}')

dateDiff=$(datecalc -a ${_date1} - ${_date2})

if [[ $dateDiff -eq 0 ]]; then
   timeCalc ${_time1} ${_time2}
fi
echo Diff in second is ${_diff} sec.

PS: datecalc you will have to get from unix.com
