I am using sprintf in the following format : [sprintf %s%s:%s%s],
which lets me have a nice clock in a LCD (or message box probably) in
a format something like 12:45, or 01:56
now when i want to see negative values ( how long to wait until
something happens...) i can easily have -10:21 (still fine) but i
would like to have also -4:39...
meaning i would like the first %s (leftmost) to output nothing......
for the moment i just output a dot (.) so my format is .-4:54... but
is there a way to input something which will be output as nothing???
