Is that one of the old XOs that had troubles with the tiny battery feeding 
the TOY/RTC clock when the main battery and wall power are both disconnected? 
 I forget the details, but I think there was a problem with the battery

NetworkManager used to call ntpdate when it setup a connection.  Was that an 
OLPC addition?

I think this area gets tangled up with security and lease checking.  Do we 
want/need two separate modes, one for the secure case and another for 
developers without a school server?

What are the school servers doing to keep their clocks reasonable?

ntp is probably overkill for XOs.  Besides, who would want to give up that 
much ram?  On top of that, ntpd doesn't get along with power saving mode.

Aside from quirks like this one, is time on the XO normally good enough?

These are my opinions, not necessarily my employer's.  I hate spam.
