I’m posting this just as an observation of something we discovered.
Bill Gates must have come in and set our recorder computer to PST. It was displaying the time correctly, both on the system clock, , the database, t_stamp, everything.
When we viewed a chart on our other computers, (set to EST) everything was 3 hours off!
Just by chance, we decided to look at the time zone setting of the recorder, When we set it to EST, everything now works OK.
