I would really like to know the use cases where chronyd is not sufficient and
the problems that people are trying to solve.
I think the purpose of saving and restoring system time from a file is
to have monotonic time on machines that don't have a network
connection or only have an intermittent connection, so messages in
logs can be sorted, make doesn't complain timestamps are in future,
etc.
