I am trying to use calculations with time in the form hh:mm - hh:mm and EXCEL
does not like negative time. The calculation is to accumulat over a week the
actual time worked by aggregating the hours worked on a daily basis. Thus at
the end of the week the time worked is ((monday time worked) XX:XX - 7:12 +
(tuesday time worked) XX:XX - 7:12, etc for the week)

Tool Options Calculation check 1904 date system
or
convert excel time to decimal by multiply by 24

Excel will happily do any calculations with times, it just won't *display* a
negative time. If you don't ever have to display a negative time, then just
do the calculations. If you do, TM has given you the options.
