Use of Timezones with Moment plugin

Question

I’m having trouble using the Timezones plugin from the Moment library, specifically, I’m not able to load the data. I need to carry the timezones of London and São Paulo, but I couldn’t quite understand that document format:

moment.tz.add([
    'America/Los_Angeles|PST PDT|80 70|0101|1Lzm0 1zb0 Op0',
    'America/New_York|EST EDT|50 40|0101|1Lz50 1zb0 Op0'
]);

There is the example, but what are these acronyms and numbers? What are the London and São Paulo?

I searched the documentation for the available data, but found nothing about.

Answer 1

I managed to solve by opening one Issue in the project. Follows the solution:

The documentation is here, but I agree that it could be more complete. We are also expecting the Data Builder for #9.

The easiest way for now is to include one of the two files available on Moment-Timezone home page, the moment-timezone-2010-2020.js ormoment-timezone-all-years.js.

If you only want specific zones, then use moment-timezone.js, and extract the zones you need from other data files, or from the archive latest.json on Github.

For 2010-2020 only:

moment.tz.add([
   "America/Sao_Paulo|BRST BRT|20 30|01010101010101010101010|1BIq0 1zd0 On0 1zd0 Rb0 1zd0 Lz0 1C10 Lz0 1C10 On0 1zd0 On0 1zd0 On0 1zd0 On0 1C10 Lz0 1C10 Lz0 1C10",
   "Europe/London|GMT BST|0 -10|01010101010101010101010|1BWp0 1qM0 WM0 1qM0 WM0 1qM0 11A0 1o00 11A0 1o00 11A0 1o00 11A0 1qM0 WM0 1qM0 WM0 1qM0 11A0 1o00 11A0 1o00"
]);

For every year:

moment.tz.add([
   "America/Sao_Paulo|LMT BRT BRST|36.s 30 20|012121212121212121212121212121212121212121212121212121212121212121212121212121212121212121212121212121212121212121212121212121212|-2glwR.w HdKR.w 1cc0 1e10 1bX0 Ezd0 So0 1vA0 Mn0 1BB0 ML0 1BB0 zX0 pTd0 PX0 2ep0 nz0 1C10 zX0 1C10 LX0 1C10 Mn0 H210 Rb0 1tB0 IL0 1Fd0 FX0 1EN0 FX0 1HB0 Lz0 1EN0 Lz0 1C10 IL0 1HB0 Db0 1HB0 On0 1zd0 On0 1zd0 Lz0 1zd0 Rb0 1wN0 Wn0 1tB0 Rb0 1tB0 WL0 1tB0 Rb0 1zd0 On0 1HB0 FX0 1C10 Lz0 1Ip0 HX0 1zd0 On0 1HB0 IL0 1wp0 On0 1C10 Lz0 1C10 On0 1zd0 On0 1zd0 Rb0 1zd0 Lz0 1C10 Lz0 1C10 On0 1zd0 On0 1zd0 On0 1zd0 On0 1C10 Lz0 1C10 Lz0 1C10 On0 1zd0 On0 1zd0 Rb0 1wp0 On0 1C10 Lz0 1C10 On0 1zd0 On0 1zd0 On0 1zd0 On0 1C10 Lz0 1C10 Lz0 1C10 Lz0 1C10 On0 1zd0 Rb0 1wp0 On0 1C10 Lz0 1C10 On0 1zd0",
