Correct me if I am wrong. From what I gather all that
you need is a method of adding multiple time slices which
you want to input from a file or interactively.
The easiest way would be to convert all to seconds,
add them all up and then convert back to hh:mm:ss.
Assuming you have a input file with data like:
....
01:10:15
00:05:08
00:12:12
....
Your script would be something like this:
----------------<snip>--------------------------
#!/bin/sh
TOTAL=0
for i in `cat $1`; do
HH=`echo $i | cut -b 1-2`; HH=$((HH*60*60))
MM=`echo $i | cut -b 4-5`; MM=$((MM*60))
SS=`echo $i | cut -b 7-8`
TOTAL=$((TOTAL+HH+MM+SS))
done
echo -en "Total Duration (hh:mm:ss) = "
echo $((TOTAL/3600)):$((TOTAL/60%60)):$((TOTAL%60))
exit
-----------------</snip>-----------------------
You need to call this script with the datafile name.

There is a need at times to know how many days have lapsed
since Jan 1 (Julian dates). The easiest way out is to use the
cal program [ Try: cal -j 10 2001 ... and have a look !]
