Mark:

I am currently running ECS Version 4.4.004.  According to the manual for
that version, and according to your post below, I should have to add 60
minutes to the sunrise-time and sunset-time to get the proper values
adjusted for daylight time.  BUT, I appear to be getting proper daylight
time values without doing any further math.  Am I doing something wrong?

Based upon Latitude=+42 , Longitude=+87, Central time zone, and today's date
(8/30/00), I am getting a sunrise of 6:12 AM and a sunset of 7:23 PM.  These
are the correct times without any further adjustment.  I don't mean to
complain about getting the right answer.  But, doesn't this mean that I will
have to create code for the opposite correction when we revert to standard
time?

Kevin
