Dick,

Your hard efforts on this program - as well as all the other gems you have 
cooked up for the ham community - are greatly appreciated!

Here's what I think is happening:

Aggregator calculates sunrise and sunset times every time it connects to
its primary skimmer.  This works fine when the primary skimmer is CW
Skimmer or CW Skimserv because Aggregator disconnects from  and
reconnects to the primary skimmer every time Aggregator rotates the ini
file.

As I recall from Dave's previous posts, one of his Aggregators uses an
instance of RTTY SkimServ for it's primary skimmer. (Dave, is this
correct?) In that case, Aggregator does not disconnect from and
reconnect to the primary skimmer when rotating .ini files.  Instead, it
sends a SKIMMER/RESTART telnet command to force using the new .ini
parameters.  In this configuration Aggregator could run for a long time
without updating the sunrise and sunset times.  Not a good thing.  I
need to fix it.

Dave previously asked me to change this so that on ini rotations
Aggregator will treat RTTY Skimserv as it does CW Skimserv.  This would
fix the current sunrise sunset problem.  But I have not made the change
yet.  My comments in the code say I had to treat RTTY Skimmer
differently but don't say why, and I can't remember. Could well be this
was a misunderstanding on my part.  I need to spend some more time
trying to figure this out.

Grid is displayed in upper case so that is ok.  both machines set to utc.



I closed the wrong one and reopened it then it now it displays the correct 
times.  I am wondering if the aggregator only calculates the sunrise/set 
once a week or something like that?  this time of year the difference could 
be several minutes a day.

Did you check the Windows Time Zone setting?



Also, does it display in uppercase as FN32LL or FN32II (eye and el look the 
same in lower case in many fonts).

I have 2 computers running skimmers, one has the correct sunrise/sunset
times  1140z/2234z, the other is wrong showing 1206z/2208z.  both show grid
as fn32ll, both clocks are showing the same date/time.  just happened to
notice because when I just checked one was still on the night ini file and
the other was on the day one.  what inputs could be different, or is one of
them just not updating the calculation for some reason???
