For example, a spot timed/dated 23Nov09 @ 2355 is at the bottom of the window with incoming spots.  A few minutes later, say 10 minutes, another spot comes in dated/timed  24Nov09 @ 0005, and rather than being at the bottom of spots window (where common sense would indicate as the correct place, it is at the top and consequently is not visible in the normally sized window.  Even if the window is maximized, it will still be out of sight.  I have my computer set for Eastern Standard Time (rather than zulu time) and I wonder if this is the issue.  If so, it's something which should be modified in DX4W as most of the other ham-related software I use works by adding/subtracting hours to/from the local time in the computer and then displays the Zulu time.

What version of DX4WIN are you running?  How are your spots sorted, by
time or by arrival?

I have my computer set to local time (not UTC) and have NOT seen this
problem, either in 1-land or 0-land.  I sort spots by time.

There are cases where a SH/DX command that does NOT contain the date
of the spots, done well after the date change, can cause the spots to
be sorted incorrectly.  For example, if it's 12z, and a SH/DX command
shows spots from late in the previous day, but the spots don't contain
a date field, DX4WIN will assume they are for the current day, and
will sort by only the TIME field accordingly.  Now this doesn't make a
lot of sense (to allow spots "from the future"), but the clock on some
cluster nodes is off by a few minutes +/-, so this can happen.  But
that's an extreme case, and doesn't sound like it's the case with your
spots.

If you use the VE7CC front-end, you can configure the spots sent to
your logging program to always be in the SH/DX format (including the
date), such the problem you describe can not occur.

But as I said, I don't do this, and my spots are sorted as expected.
