Anything approaching 1 full second after 30 minutes still seems
significant. By comparison, the worst case drift for Hi-MD/MD would
be around 1/20 of a second after 30 minutes.

You could fully charge your LS-10 and record for three hours or as
long as you can at 16/48 or 16/44.  For an accurate time reference,
record the Universal Time announcement at start-up and every hour or
so using one of these phone numbers (303) 499-7111 for WWV
(Colorado), or (808) 335-4363 for WWVH (Hawaii). Compare the audio
announcements to the time line of an editing app like Audacity.

I have no idea as to the cause. Doesn't seem likely that the
electronics would have variable drift from a battery voltage drop or
anything like that.  It possible that the drift could be constant--
that is-- its clock could generate the same, off-standard time with
each use. That might be correctable if needed. Rob D.
