Hi all, We completed the transition of the Intl handling from using OS locale, to use browser UI locale.
We have a new API called mozIntl.DateTimeFormat which should be the primary way we format date and time in our chrome. You can think of it as a regular ECMA402 DateTimeFormat on steroids. It gives us two "shorthand" options "dateStyle" and "timeStyle" which you can use instead of listing manually all options. This should lead to increased consistency of our UI. On top of that, those two options allow us to tap into OS regional settings to read any manual adjustments user made and respect them. Imagine that the user changed time format from hour12 to hour24. mozIntl.DateTimeFormat will respect that and show the time in the current UI locale, but with this adjustment. This step is crucial for better product localizability (because now the dates are in the same language as the rest of UI - think "Today is: April 5th" where "April 5th" comes from date formatting and "Today is:" from l10n - we want both to be in one language). Example of how to use the new API: ``` let dtf = mozIntl.createDateTimeFormat(undefined, { dateStyle: 'long', // full | long | medium | short timeStyle: 'medium // full | long | medium | short }); dtf.format(now); ``` Please, use the new API for all new code and when possible, migrate old code to use it. Thanks! zb. _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
