+
+If you manually set the time manually then doing the sync to RTC makes
+sense. However, what does not make sense is doing it at shutdown/startup
+unconditionally.
+
+This is why the kernel will automatically does the sync for you every 12
+minutes when an ntp daemon is running. This is the recommended method.
+
+So unless we have a proper frame of reference, (user set time, ntp
+protocol time) then there should be no manual sync.
+
+Aside from this, the fact that e2fsck uses the current time as one of
+it's checks is just daft in the first place. If I have to replace the
+battery in my motherboard I don't want to have to get a bogus fsck
+warning. The change should stand in it's own right as being a sensible one.
