It makes sense. Thanks. So if I set it to October 31, 00:59:00 and wait for an hour I should see the transition, right? Thanks a lot. bww@acm.org To: RBallen@hypercom.com 05/26/04 08:21 AM cc: Subject: Re: Beginner questions

Then, I set my local time to October 31, 1:59 and I double checked that localtime() was in fact giving me 1:59. Two minutes later I was expecting the wall clock to go back one hour. It didn't. What am I doing wrong?

There are two 01:59's on that day ... you set the time to the second, after which there is no transition.
