I tried updating the clock for daylight savings last week and found that the clock on the high-level LCD didn't change.

It appears this is related to the "GPS Week number rollover" that happened last year:

The satnav system thinks its in 2001.

As far as I know, unless Honda creates an update, the only way to set the time is to disconnect the battery and reconnect at 1:00 (the clock resets to 1:00).
