<p>Hi,<br>
</p>
<p><br>
</p>
<p>I think the tzdb is very good with its history. However, I would like to minimize the size and has been looking into how to achieve that.<br>
</p>
<p><br>
</p>
<p>Will it be of any interest with an option in zic to include only data from a certain year onward?<br>
</p>
<p><br>
</p>
<p>What is the best way?<br>
</p>
<p>1. Remove the Rules and Zone entries not relevant for that year onward during the parsing. Tried this, but ended up with with some nasty warnings.<br>
</p>
<p>2. Make changes in writezone-function. Trying this now, but I am getting confused with types, omittype, typemap, and so on.<br>
</p>
<p><br>
</p>
<p>It would be good if someone that knows the code can give me some hints if this is the right place to make such a change.<br>
</p>

<p>BR,<br>
