Errors in RRULE examples in RFC2445?

["Shriram V" <shriram_vishwanathan@xxxxxxxxxxxxxxxx>]

Hi all,


Is this an error in the RRULE examples in RFC 2445, in section 4.8.5.4?

I have found that two of the rules in the RFC include the last occurrence,
even though it occurs later than the UNTIL date-time.

I tried searching though the mailing list archives, but could not find any
previous postings on these errors.

[Page 119]
Everyday in January, for 3 years:

     DTSTART;TZID=US-Eastern:19980101T090000
     RRULE:FREQ=YEARLY;UNTIL=20000131T090000Z;
      BYMONTH=1;BYDAY=SU,MO,TU,WE,TH,FR,SA
     or
     RRULE:FREQ=DAILY;UNTIL=20000131T090000Z;BYMONTH=1

     ==> (1998 9:00 AM EDT)January 1-31
         (1999 9:00 AM EDT)January 1-31
         (2000 9:00 AM EDT)January 1-31
=======

1. It should be EST instead of EDT? (A typo?)
2. Last occurrence (2000 09:00 Jan 31) should not be included.

The last occurrence is on (2000 09:00 EST Jan 31)
which is equivalent to    (2000 14:00 UTC Jan 31).

This is definitely later than UNTIL (2000 09:00 UTC Jan 31),
so should be excluded.

Every 3 hours from 9:00 AM to 5:00 PM on a specific day:

     DTSTART;TZID=US-Eastern:19970902T090000
     RRULE:FREQ=HOURLY;INTERVAL=3;UNTIL=19970902T170000Z

     ==> (September 2, 1997 EDT)09:00,12:00,15:00
=======


1. Again last occurrence (1997 15:00 PM Sep 2) should not be included.

The last occurrence is on (1997 15:00 EDT Sep 2)
which is equivalent to    (1997 19:00 UTC Sep 2).

This is definitely later than UNTIL (1997 17:00 UTC Sep 2),
so should be excluded.





Somebody please comment.
Let me know if my interpretation is correct or not?



Thanks,
Shriram.
