This program sums the times in the list with end times (positive) and start times (negative) for work days in a week. The times are given in the sexagesimal format h.mmss i.e. 14:50:00 is 14.5000 and -07:45:06.18 is -7.450618. The result is also in sexagesimal. It could be used to compute working hours for jobs with flexible hours per day. NO WARRANTY.
