Today is the last day of October and I have just tried to programme my 5000T for BBC1SD for the news at 1735 tomorrow (1st Nov) to cover both main and local news (25 minutes).
I set all the correct parameters and the date definitely said 1/11, but when I entered it there was nothing showing for it in the schedule. I then tried again and got a recording conflict for 1st December.
I found that the only way I could get it right was to reschedule the "1/12" recording to 1/11 and it worked.
I wonder if anyone else has noticed this at a month's end or can reproduce it.
