But did not receive any suggestions for troubleshooting.

I've been checking since then and have discovered it apparently works
intermittently. but only a few snapshots are taken.

I'm pretty sure that was following a reboot and time-slider worked for
a short time.  The reboot was not related to timeslider investigation
and I didn't think to immediately check how timeslider was performing.

But did notice the Timeslider icon in upper right of Mate desktop quit
flashing, but then started up again after a .5 hr or so.

But then in some locations I see a regular (the expected) progression
of snaps.

I'd really really like to get it working... after all it is one of the
big plus's for running OI/hipster.

Checking time-slider log I see dozens of lines like these, but for
some unfathomable reason the lines are not dated so not able to
pinpoint when this happens:

to pinpoint when this occurs, other than from the date in snapshot
filename. 

But still cannot tell what is really going on.

I see there are regular consecutive time-slider created logs at
/.zfs/snapshot/*   But not in many other locations... whereas
time-slider is configured for `ALL'

How can I trouble shoot this?
