http://shorturl.at/adiZ4 Spec https://github.com/tc39/ecma402/pull/347 TAG
review No TAG review since the TC39 and ECMA402 will cover that. Summary
Enhance the Intl.DateTimeFormat API by adding a “ fractionalSecondDigits”
option to control the format of fractions of a second. Link to “Intent to
Prototype” blink-dev discussion
https://groups.google.com/a/chromium.org/forum/#!searchin/blink-dev/Intent$20to$20Implement$3A$20Add$20millisecondDigits$20option$20to$20Intl.DateTimeFormat%7Csort:date/blink-dev/WXd9nh03a1M/z7QeIMgrBgAJ
Risks
Interoperability and Compatibility low. *Firefox*: Public support (
https://bugzilla.mozilla.org/show_bug.cgi?id=1568134) *Edge*: No public
signals *Safari*: No public signals *Web developers*: No signals Ergonomics
Part of the pre-existing ICU functionality w/o need of additional data.
Activation Should be easy to use by using w/ pre-existing
Intl.DateTimeFormat Security low
Debuggability nothing special. Will this feature be supported on all six
Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android
WebView)? Yes Is this feature fully tested by web-platform-tests
<https://chromium.googlesource.com/chromium/src/+/master/docs/testing/web_platform_tests.md>
? Yes Tests are added to test262
