V1.1.1 unable to set time

The v1.1.1 firmware update has been working well for me, for the most part. I am, however, unable to statically set the time. The date/time fields look grayed out, but it does allow me to change the values. These changes aren’t set once I save them, the revert to the previous values (approximately 18 hours different). Setting the time zone works properly. I am not connected to a WiFi network.

Not a major deal, just sort of annoying.
