I have the programming sofware for the mx850 but I don't think it has a timer or clock. I am not sure.. I am very familiar with programming of the mx850 - I have been using it for many years.. I did want a timer and I could not see anyway I could do that.. I tried a sequence of 30 sec delay codes into a macro and it did not work out for me.. Besides, its not a good one. Many new computers do not have rs 232 connection.. I don't know about the mx900.. but any universal remote today should have the blue, red, yellow, green hard buttons.. Besides, the 850 does not even have the 30 sec skip button.. That is really silly.. DVRs had already been in existence before they made the 850..

If you do find a remote with a timer, let me know. I am looking at harmony 900 but I am not sure it has a sleep timer..
