[I] Mouseover tooltip on temporal chart should include year [superset]
sfirke opened a new issue, #44149:
URL: https://github.com/apache/superset/issues/44149
### Bug description
On a scatterplot spanning multiple years, and presumably other temporal charts, only the day and month are visible in the tooltip when I mouseover a point. I have to look down to the x-axis to see what year I'm in. This chart spans 2014-2026 so it's not obvious what year I'm in when I mouse over a point.

I would like to see "Thu Mar 20 2016".

I dug into where this comes from: the tooltip's temporal x value renders through the `smart_date_verbose` formatter (`superset-frontend/packages/superset-ui-core/src/time-format/formatters/smartDateVerbose.ts`), whose day/week tiers are `'%a %b %-e'` — that's the "Thu Mar 20" (missing year) on this chart. Because the multi-formatter picks its tier from the date's own granularity (a midnight timestamp hits the `day` tier), a 2014–2026 scatter still drops the year.
Before opening a PR I'd like a steer on the intended fix, since `smart_date_verbose` is shared ("Verbose Adaptative Formatting"): should the day/week tiers become e.g. `'%a %b %-e %Y'` globally — simple, but it also lengthens every surface using that preset — or should the year be range-aware (include `%Y` when the x-domain spans multiple years) and scoped to chart tooltips only, which needs the chart range plumbed into the tooltip formatter? The reporter's example ("Thu Mar 20 2016") suggests the global tier change, but I don't want to churn a widely-used formatter without a maintainer weighing in. Happy to implement either direction with a small unit test on the formatter.

Good question. What is the list of charts that would be affected if we made
the change globally?

#44212 implements this. Here's the global-impact list:
It's narrower than "everything with a time axis" — x-axis tick labels use the non-verbose `smart_date` preset (`getXAxisFormatter`), which stays untouched. `smart_date_verbose` renders in exactly 4 surfaces:
1. **Time-series family tooltips** (Timeseries incl. scatter, Mixed Timeseries, Gantt) via `getTooltipTimeFormatter` — only when "Tooltip time format" is left at the default "Adaptive formatting" and no time grain is set; with a grain, tooltips already include the year (`2021-01-07` for a day grain)
2. **Time Pivot** — tooltip time labels
3. **Big Number** (time-series mode) — the "Show timestamp" line under the metric
Month/year tiers are already year-bearing (`Mar 2020`, `2020`), and users with an explicit d3 format in the control are unaffected — so the whole visible delta is: daily/weekly tooltip stamps on those surfaces gain a year.
Since that scope is tooltip/timestamp-only, the PR makes the global tier change (`'%a %b %-e'` → `'%a %b %-e %Y'`), so hovering a daily point reads "Thu Mar 20 2016" exactly as in the report. Happy to switch to a range-aware variant if single-year charts should stay terse.
