The Pine64+ 2GB that I have access to still is
operating fine for the date/time:
# uname -apKU
FreeBSD pine64 12.0-CURRENT FreeBSD 12.0-CURRENT r324743M arm64 aarch64 1200051 1200051
# uptime
5:59AM up 16 days, 12:49, 2 users, load averages: 0.04, 0.07, 0.07
(It has been largely idle over much of
that time, but did svnlite update /usr/ports
and poudriere bulk related to what I
later list.)

It might be appropriate to back things off to
near-default and see if the time keeping is
then okay. (Compare to what I have, for
example.) Sitting idle might be part of this
experiment.
If it is okay, then gradually reintroduce things,
monitoring for time problems between, until
time starts to be a problem. Back off the
recent additions and then keep gradually
adding other things. See what all you can
have without having time problems vs. what
leads to problems.
Of course if the near-default still has time
problems sitting idle it would suggest something
more basic in your context is involved,
possibly hardware or a bad ntp time source.
