Thanks for sharing your discovery.
Changing TZ=CST5CDT to TZ=CST6CDT makes perfect sense out of your problem.
The actual time setting & time zone (CST) was correct on both your UNIX box and PC.
The problem was the relative time change value of 5 hours which should of been 6 hours.
That likely explains why everything looks great on each of the boxes (PC & UNIX box) but only has a problem when the 2 boxes adjust the time between each other.
The problem is so well hidden it almost seems like someone was playing a practicle joke on you.
I say that becuase I had to work my way through some practicle jokes when I first came to work here.
A couple of them I thought were pretty good were:
– when I launched an xterm there were no letters because the forground and background had been set to the same color, which makes it hard to debug without any visible text.
– putting tape over the inside of my phone receiver so I could here the caller but the caller couldn’t here me.
I can see why it took some time to figure out the puzzle.
Did you laugh or cry when you made the discovery because I found it a bit amusing.
I was curious to locate my TZ=CST6CDT setting and found it located in /etc/environment on our AIX box.
