Response from Harmony, impressed with the speed of their answer, however, not impressed with their lack of support.
Thank you for your recent inquiry about your Harmony Remote
We are sorry to hear that you are having some trouble setting the time on your Harmony 880 remote control. We are aware of this issue, and are working to correct it. The fix for this will actually come not through a firmware update, but through an update to our web servers. Unfortunately, there is no expected completion date for this.
Any updates are posted to the Important Information section of the Login screen of the Harmony Remote control software. Once this is corrected, you will see the note added to that area. At this point, we recommend that you check back in a few months for the fix. We apologize for any inconvenience this may have caused.
