Subject: [guide-user] DST fix posted
> Hi folks,
>
> I've posted a fix for the DST problem, at

> http://www.projectpluto.com/new.htm
>
> HOWEVER, be advised that if you wait until Sunday,
> the problem will go away. Turns out there's a problem
> with certain versions of the Microsoft C runtime library:
> if DST begins in a month that starts on Sunday, it waits
> a week before instituting the DST changeover. Hence,
> according to Microsoft, DST will not occur until 15 March,
> not 8 March. (And yes, I'm ready for the inevitable
> "beware the ides of March!" comments.)

> The bug affects certain time functions, but not all.
> That's why I found myself staring in bemusement at some test
> code I wrote, which showed that different time functions
> in the Microsoft library were returning different times.
> Fortunately, Bill Appelbaum e-mailed me about this, and
> described the problem. He adds: "We haven't had a March
> or November starting on Sunday since 1998, so the bug hasn't
> manifested itself until now."

> March and November always start on the same day of the
> week, so if you face the problem in March, you'll have it
> again in November.

> Many thanks to all who replied on this issue. I've had
> several reasons to curse DST over the years. Guess I can
> add this to the list.
