      Thanks Arthur.

Sean and I've faced this issue while working on 2010c in JRE.

Subject: Re: proposed time zone package changes--Paraguay, core dump avoidance
Hi Arthur,
Can I ask why you used the follow logic for the new Asuncion rule :
Rule       Para    2010    max     -       Oct     Sun<=7  0:00    1:00    S
instead of keeping with tradition and using something like :
Rule       Para    2010    max     -       Oct     Sun>=1  0:00    1:00    S
"Sun<=7" is the first instance of such a rule in the Olson files and 
causes an issue
with the JRE when it parses Olson rules . (something that can be 
modified on the java side I guess)
Is it possible to use Sun>=1 for 2010d ?
regards,
Sean.

Below find proposed changes to the time zone package:
localtime.c	more core dump avoidance work
  southamerica	changes to Paraguay DST rules from 2010 forward
If no problems are found, these are to show up on the ftp site on 2010-03-01.
(I'm trying to get a good reference before making Bangladesh changes;
I'm trying to get starting- and ending-time-of-day information--and trying
to learn whether or not DST was actually observed in 2009--before making
Samoa changes.)
