System time stuck after returning from deep sleep

Question

Hi,
When I return from deep sleep, my system time is set to when I entered deep sleep. Only after opening Date & Time system preferences, the time is corrected.
Any help is highly appreciated.

Other basic and routine maintenance is often helpful
even if the results of preventative tasks go unseen.
The use of Disk Utility's function to 'repair disk permission'
and also the ability to start the computer into SafeBoot
mode, where it is forced to check and repair system bits,
(hold shift key on startup, wait, login; at desktop, you can
also choose to run Disk Utility per above, by using GO in
the Finder menubar, and open Utilities folder> disk utility;
when done repairing disk permissions, quit; then restart)
is one of the harmless simpler single or dual acts one can do.
There are third party utility like interface tools that allow
the user to run maintenance tasks through the GUI of
that tool and not have to force them from a Single User
mode of access; these are often freeware, such as the
well known OnyX by Titanium Software. In my Macs,
once a month or more (if I feel motivated) I run OnyX's
'automation' tab selection, and check-box all of them.
And have OnyX's preferences set to restart after its done.
Some of the other options can be helpful, when you discover
their purpose and find when they can have practical worth.
In any event, some kinds of issues can be headed off; and
a good idea is to invest in some backup strategy which
gives you a few options; although I am lazy about it now, I
have made backup full bootable clones of my computers.
This is done to an external drive which supports same.
Learning ahead of a drastic need, how to use some of
the better free-running downloadable cloneware, is good.
And the idea is you can actually do most of the minor tech
work and repairs to a system (and have boot clones) at
home; especially handy when you live 100+ miles on a
road to nowhere. As some will argue, the living planet is
on a dead-end road, it is good to get out and witness life.
Being where there are no tech support persons, I have
learned to do more than I need to; and when not messed
with, tend to enjoy learning more than I'd actually need to.
In any event, hopefully things go well with these matters...
Good luck & happy computing!
