Comment 9 for bug 1328646

Confirmed on Utopic 161.

I unplugged the mako from USB, turned its screen off, and let it sit for 10 minutes next to a computer with a known-good clock. When I turned it back on, its clock updated within one second from T-2m to T-1m -- that is, it was just over a minute behind, after being idle for only 10 minutes. About 20 seconds later the clock updated again to the current time. I assume that was when NTP kicked in.

So, it seems that the clock gets behind at a rate of roughly 6 seconds per minute. That's pretty bad, as far as clocks go. And it presumably doesn't update until it can get online.
