Subject: [PATCH 0/7] hwclock patch cover letter.
Date: Sat, 27 Sep 2014 11:16:18 -0400	[thread overview]
Message-ID: <5426D4C2.4060403@gmx.com> (raw)

This hwclock patch set includes three topics, one
is needed functionality, the other two are bug
fixes.

The first also fixes three bugs as a side effect
(See 'Part II' in its commit message).

The second fixes a complaint we receive regularly
from users that keep their Hardware Clock set to
the local timescale while running NTP.

Note: to test this fix you will need a kernel >= 3.13,
as 11 minute mode was broken from 3.0 ~ 3.13-rc1.

The third involves the use of --systohc at
shutdown. We need this with 11 minute mode to
refresh the adjtime file's timestamps, but doing
so clobbers the drift factor to near zero.  When
not running NTP it causes drift factor creep by
assuming that the System Clock is keeping perfect
time. Of course, it is not.
