I know it is possible to use tzupdater.jar to update a timezone database in the JVM, and I've no doubt that changing daylight savings times (by editing rules in the IANA database) is a fairly easy thing to do.
However, and regardless of whether or not this is a good thing to do in practice, I would like to know if it is possible to omit entire continents or just some / combinations from tzdb.dat.
Can the IANA distribution be edited to do this and, if so, how ?
Thanks
