proposed time zone package changes (Bahia de Banderas; version naming)

[Olson, Arthur David (NIH/NCI) [E]]

The second line from the bottom should indeed be...

                        -7:00   Mexico  M%sT    2010 Apr 4 2:00

...and I plan to get it corrected in the next release.

I saw the new zone above in tzdata2010j.  The last 2 rule lines produce 
two transitions around Apr 4, 2010.

I use zdump (a little bit modified just for formatting outputs) to detect 
transitions and below is the result.

2010-04-03 Sat 23:59:59-0700[DST=0] > 2010-04-04 Sun 01:00:00-0600[DST=0]
2010-04-04 Sun 01:59:59-0600[DST=0] > 2010-04-04 Sun 03:00:00-0500[DST=1]

I guess the second line from the bottom would be - 

                        -7:00   Mexico  M%sT    2010 Apr 4 2:00


I'm wondering if this is intended, or just a bug.
