Subject: Japan's rules

It seems that Japan is missing its latest rule.  The last rule it has is

<Rule>
      <Name>Japan</Name>
      <From>1950</From>
      <To>1951</To>
      <Type>-</Type>
      <In>May</In>
      <On>Sun&gt;=1</On>
      <At>2:00</At>
      <Save>1:00</Save>
      <Letter>D</Letter>
    </Rule>

And the timezone is defined as:

<Zone>
      <Name>Asia/Tokyo</Name>
      <GMTOffset>9:00</GMTOffset>
      <Rules>Japan</Rules>
      <Format>J%sT</Format>
      <Until />
      <Comment />
</Zone>

This forces the user to use JDT as the timezone abbreviation even though I believe they currently don't do daylight savings time.
It seems this should be updated to:

<Zone>
      <Name>Asia/Tokyo</Name>
      <GMTOffset>9:00</GMTOffset>
      <Rules>Japan</Rules>
      <Format>J%sT</Format>
      <Until>1951</Until>
      <Comment />
</Zone>
<Zone>
      <Name>Asia/Tokyo</Name>
      <GMTOffset>9:00</GMTOffset>
      <Rules>-</Rules>
      <Format>JST</Format>
      <Until />
      <Comment />
</Zone>

Does this make sense?
Thanks,
