Timezone DB Bug

[azampagl]

Describe the bug I'm not sure if this is a day.js bug or a native browser Internationalization API bug, but the time zone database seems to be out of date.

For example, if you apply the following timezone in day.js

dayjs.tz('2022-11-08 13:00:00', 'America/Ojinaga')

You will get an offset of UTC -7.

Expected behavior

The offset should be UTC -6.

https://timezonedb.com/time-zones/America/Ojinaga

(They city of Ciudad Juárez, Mexico recently changed this)

If day.js is not the proper place to report this bug, do you know where to file a bug report for the Internationalization API?

Information

• Day.js Version: 1.11.6
• OS: All
• Browser 107.0.5304.107 (Official Build) (64-bit)
• Time zone: 11/9/2022 6:51 AM EST

I am also experiencing problems with it. Thanks for creating an entry for this.

My temporary solution is to use dayjs().utcOffset(-6)

This is not a dayjs issue, but a Intl issue and should be fixed there (wherever this may be :-).

I think Intl is where the problem exists, they supposedly use IANA database and this appears to be updated (https://time.is)
