I take that back. There is no _easy_ way.
Thanks to Paul Fox for the idea.

Hi,
I ran Clock-12.5 on 11.3.1, 12.1.0 and 13.2.0 build 11, all on the
same XO-1, to see if we have any difference in startup time. This is a
GTK2 activity.
Launching 10 times from hot caches and averaging, my measurements are:
11.3.1: 12.52 seconds
12.1.0: 11.53 seconds
13.2.0: 11.74 seconds
It seems okay to me on first reading.

we get to that point. The DT is missing regulator information so the
MMC controller doesn't get powered up. This is the "old firmware, new
kernel" problem.
The DT clock changes described here would also mean that new firmwares

Hi Mitch,
As mentioned, upstream now has APBC/APMU clock drivers, and I think there
are a couple of things in way that clock-dt.c interacts with the common
clock framework that upstream wouldn't approve of.
Here is my first attempt at a new approach, using the new upstream clock
drivers

It is the tweaking of the clock state that causes instability. The
clocks in question are configured by IO Port 3C5.1B ("Power Management
Control 1"), bits 5:4 (IGA1) and 7:6 (IG

So I restructured it a bit, mainly to take the focus away from the

As you say, if the clients s

My point was that there are reasonable setups where the time in the
lease is known to be correct, but that the time on the server that
dishes the leases out over port 191 (the XS) might have a bad clock.

Multi-keys and delegation are orthogonal.

Yes, the time is asked _after_ we get a response for the lease, but it
has to be set _before_ we validate the lease.
Otherwise, the lease validation would fail with a corrupt clock.
There is a (desired) side-effect to this as well: XOs with marginal
RTC ba
1 can update the hardware clock on the XO. If it received any data
at all in response to the original "" message, the initramfs will
now send a 2nd message to the oats server with the string "time01:

that moment.

/etc/init.d/halt calls hwclock to write the current time out to the hardware.

FWIIW, the hardware clock configuration is set to use localtime by
default. This can be reconfigured to use UTC (see /etc/rc.sysinit which
includes the config file /etc/sysconfig/clock if it exists), but it
probably isn't worth the effort.
