Hi Simone,
from your output, I'd say that the schedule constructor first
generates all dates with the given frequency, adjusts them using the
Preceding convention (which moves Saturday and Sunday to Friday) but
doesn't check for duplicates. You're probably the first to try
building a daily schedule, so the problem never surfaced before...
I'd say it's a bug. How do you think this should work? Should we just
remove the duplicates?
