I am reporting this as a bug, as this is now the 4th time I have seen this now in the last 2 months.
The first character in the date is missing. For example today it said " onday, October 29, 2012" instead of "Monday, October 29, 2012". Power cycling the unit always corrects.
I have seen this now on both HD220 and HD1020 units, this one is running 4.2.26 right now I think, and the last time I saw this they were running 4.1.35 probably. Also not specific to a particular zone layout.
Hopefully it is something easy to track down.
