I see you have already thought of everything!!

Perfect, indeed :)

Great. Here is my function if someone wants it:

FSET subst_1(a, d, t) iif(d!=today(), subst_b(a, d, t), \
                   t == now(), "maintenant", \
                   t > now(), "dans " + subst_tdiff((t-now())/60, (t-now())%60), \
                   "il y a " + subst_tdiff ((now()-t)/60, (now()-t)%60))

By the way, I read:
"subst_N(alt, date, time): This is actually a family of functions, where N is a letter or number.  This function completely overrides the substitution sequence "%X".  The three arguments are an integer  alt  which,  if non-zero, indicates that the alternate-mode substitution sequence "%*X" was encountered; date which is the trigger date of the reminder and time which is the trigger time."

Instead of writing "%X" or "%*X" , maybe it would be more logical to write "%N" or "%*N" since the function is about generically called "subst_N", no? :)

Thank you & Best regards,
