# `Intl.DurationFormat` update and normative PRs ### Ben Allen, 102nd TC39 --- ### This is very much *not* a 30 minute update * (honestly, it's closer to five minutes) --- # Not a 30 minute update * We remain perilously close to asking for Stage 4 for DurationFormat * Editorial refactor in progress * We have one small normative PR * Adding testing for recent normative PRs --- ### Turn useGrouping false for hours & smaller units when style is 2-digits or numeric https://github.com/tc39/proposal-intl-duration-format/pull/198 * Fixes edge case: previously digital-clock styles (`"numeric"` and`"2-digit"`) would format very long hour, minute, and second values using grouping separators * This badly breaks the "digital clock" metaphor * Change approved by TG2 * (see example next slide) --- ### Example ```javascript df.format({hours: 20, minutes: 3, seconds: 1234567}) // Old: 20:03:1,234,567 // New: 20:03:1234567 ```
