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

  • Why do you need that? I'm not sure if it's possible, but if you could provide more info about what you're trying to do, maybe people can suggest alternatives. –  Jun 23 '17 at 15:59

    The IANA database is just text. The format is well known and documented. I don't know how to answer your question other than "Yes, use a text editor". – Matt Johnson-Pint Jun 23 '17 at 17:47
