I have a machine whose RTC clock is drifting significantly and it is
often suspended for several days. I run NTP so the drift I see when
I wake the machine up gets fixed by "stepping" the clock after a
while, but that can take a while and I'd like to improve this
intermediate situation.
It seems to me that a lot of people much smarter than I have have
wrestled with this problem for more than 50 years, and still don't have
an instantaneous solution.
Other solutions:
* Don't suspend the machine. Problem solved.
* If you must suspend the machine, bring it up some reasonable length
of time before you require accuracy from your clock. Problem solved.
* Invest in a decent GPS receiver, and install chrony and gpsd on the
machine. Doing so may get the system clock in synch faster; it may
not. Doing that sort of thing is well documented on the gpsd home
page.
Wouldn't you need to know how fast the laptop is travelling?
