Adding a List of Times

Hey gang, I have a list of times I need to sum up. This list can vary from a few to a few thousand entries. Now I had found a closed reference to adding time titled "add up time with xx:yy format in bash how?" In it, the example works great for that formatted list of times... This is the reply code from user AGAMA in that thread:

Code:
list="1:11 0:13 2:06 1:38 1:36 0:06 0:31 0:33 0:38 0:44"

h=0
m=0
for x in ${list}
do
    h=$(( h + ${x%%:*} ))   # add hours and minutes
    m=$(( m + ${x##*:} ))
done

h=$(( h + (m /60) ))    # minutes are likely more than 60, calc hours and add in 
m=$(( m % 60 ))     # adjust minutes

echo "${h}hrs ${m}min

"

BUT what I'm getting hung up on is how would I introduce the third parameter of seconds to this, if my times had the three columns?

I'm not quite verse enough in scripting to understand the formatting of the read in the 'do' loop. Are the '%' and '#' arbitrary or necessary for what they're representing?

In the other thread Agama tries to explain parameter expansion in a latter reply, but try as I may, I'm not wrapping my shrunken brain around this. I do need a bit of assistance trying to figure it out and adding in the seconds to tally up.

Thank you.

TIMES(2)							System Calls Manual							  TIMES(2)

NAME
times - get process times SYNOPSIS
#include <sys/types.h> #include <sys/times.h> #include <time.h> int times(struct tms *buffer) DESCRIPTION
Times returns time-accounting information for the current process and for the terminated child processes of the current process. All times are in 1/CLOCKS_PER_SEC seconds. This is the structure returned by times: struct tms { clock_t tms_utime; /* user time for this process */ clock_t tms_stime; /* system time for this process */ clock_t tms_cutime; /* children's user time */ clock_t tms_cstime; /* children's system time */ }; The user time is the number of clock ticks used by a process on its own computations. The system time is the number of clock ticks spent inside the kernel on behalf of a process. This does not include time spent waiting for I/O to happen, only actual CPU instruction times. The children times are the sum of the children's process times and their children's times. RETURN
Times returns 0 on success, otherwise -1 with the error code stored into the global variable errno. ERRORS
The following error code may be set in errno: [EFAULT] The address specified by the buffer parameter is not in a valid part of the process address space. SEE ALSO
time(1), wait(2), time(2). 4th Berkeley Distribution May 9, 1985 TIMES(2)
All times are GMT -4. The time now is 01:48 AM.
