Uh.. this is one of the situations where I can just say 'Wow, thanks!'. That's
a huge lot more than I even dared to expect!

The function I want to put this into (\Fee from the invoice package), is failing
no matter if I try to put \timediff10:15-16:00 into it directly:

                     \let
  l.47 ...cd.de}     {12.5}   {\timediff10:15-16:00}

try to put it into a variable with
  \newcounter{X}
  \setcounter{X}{\timediff10:15-16:00}

                     \let
  l.40 \setcounter{X}{\timediff10:15-16:00}

so I am assuming there is some magic escape I need to cast a function
call into a variable? I am looking around the web to find out, atm. :)

If anyone wants to look at the source, I included a basic example mixed
of the invoice package & your function.


Again, thanks!
Richard
