Thanks for all the replies.
I was not looking for an answer so maybe I should not have posted the problem here. I encountered the day-of-by-one error in my software and investigated the issue. When I discovered it was in the TI Standard Library, I wanted to let others know of the problem.
It's not an epoch problem. It's not a timezone problem. The problem is an improper value being set by localtime. The localtime function is returning a day value that is one too much. I know what is causing the problem and I have a workaround. No further responses needed.
Thanks again to everyone for their quick replies.
Regards,
Bruce
