<br>
I'm developing for a pretty small-sized embedded system, and 2.9M of<br>
binaries is a bit too much for us.<br>
The system never uses a date before 2007.<br>
<br>
I estimate I can slim it down too 500K by cutting down the old data.<br>
<br>
1. I made a script to cut down the source data: all the rules and all<br>
the zonelines before 2001.<br>
Compiling this data, I get a lot of errors like:<br>
<br>
> "northamerica", line 2537: %s in ruleless zone<br>
> "northamerica", line 2618: unruly zone<br>
<br>
because some zones are left without rules, but with %s format in them.<br>
<br>
2. I tried to modify zic itself, but apparently understanding it will<br>
take me days.<br>
Just setting min_year to 2001 results in bunch of<br>
<br>
> can't determine time zone abbreviation to use just after until time<br>
<br>
Does anyone have a ready solution?<br>
Thanks!<br>
