Introducing timesum

timesum is a little tool to add up times; something which I am getting used to working at a consultancy. It accepts a number of arguments which are interpreted as minutes and then it will sum those and print them out as hours and minutes;

./timesum 07:30-10:30 1:30 1.25
05:45

It is distributed as C source so should be easy to build on most UNIX-like environments. You can find it here.
