Error in timezone data

I believe I found an error in the summer-time rules for Uruguay.  The
latest version of the data (1997g) has the following as the last few
lines of the Uruguay rule:

Rule	Uruguay	1989	only	-	Mar	12	 0:00	0	-
Rule	Uruguay	1989	only	-	Oct	29	 0:00	1:00	S
Rule	Uruguay	1990	1992	-	Mar	Sun>=1	 0:00	0	-
Rule	Uruguay	1990	1991	-	Oct	Sun>=21	 0:00	1:00	S
Rule	Uruguay	1992	1993	-	Oct	Sun>=15	 0:00	1:00	S
Rule	Uruguay	1993	only	-	Feb	28	 0:00	0	-

I think the intent is to stop observing summer time after 1993 Feb 28.
However, the effect is to keep summer time forever after 1993 Oct.  I
believe the next-to-last line should read:

Rule	Uruguay	1992	only	-	Oct	Sun>=15	 0:00	1:00	S

That way, the change to standard time on 1993 Feb 28 is the last rule
executed.


On a personal note, I just want to thank you for going to all the
trouble of compiling this vast repository of time zone information.
I couldn't imagine trying to pull all this together myself.  Thanks
also for supplying it so freely to the Internet community.
