I often use the Alt+T to display the time. I only turn on the wireless when am going to download books, so am wondering how accurate it is. I'm assuming the time is corrected via the Whispernet, yes?

I hope it is more accurate than computers' clocks. :D

So far it's seemed pretty accurate to me. I checked it a couple of times after not using the wireless for a few days against the clock next to my bed which sets via RDS and they were the same.
