Something you might consider to make the time delta _less_ drastic, is to create a service which on system shutdown touches a file {in /etc/} and on boot early in the start-up {make some other services depend on it} checks to see if the system date&time is before the time on that file, if it is then use the time stamp {+ a few sec} on the file to set the current time. That way time would at least move forward. in the olden days we used to use `hwclock --badyear` mitigate part of it. perhaps you could extend hwclock for --dead-batteries and make it easier for every one with an arm {assuming hwclock is still used in the boot process to pull the initial time from the clock}. :) Even when this disclaimer is not here: I am not a contracting officer.
