    Reducing js-joda-timezone file size

    If you don't need all the historical data that js-joda-timezone provides, you can instead use one of the reduced files ize builds:

    • js-joda-timezone-10-year-range.js covers +- five years from the current version's release
    • js-joda-timezone-1970-2030.js covers from 1970 to 2030
    • js-joda-timezone-2012-2022.js covers from 2012 to 2022

    To use one of these, just change your import path to the following format:

    import 'js-joda-timezone/dist/js-joda-timezone-1970-2030'
