A one-time event opened for editing said "this is a recurring event —
changes apply to the whole series", and deleting one offered to delete
all occurrences of an event that has exactly one.
Three places asked whether an event had a baseEventId and took that for
recurrence. It isn't: the calendar loads its range with expandRecurrences,
and Stalwart puts a baseEventId on everything it returns that way, a
one-off pointing at itself included. The mock never sets the field at
all, which is why this only showed up against a real server.
They now share isRecurring(), which asks about recurrence rules, and
treats a base that is some other event as an occurrence of a series too
— so an expanded instance that travels without its rules is still
described honestly on the way to being deleted.
Fixes#25
Browsers render <input type="date"> and datetime-local in their own locale and
ignore the page's, so #1 left a German user on an English browser reading
22.11.2025 everywhere but still entering dates through an mm/dd/yyyy widget.
#3 makes the case that people use the picker rather than typing, which is
where the AM/PM mistakes happen.
New DateField and DateTimeField (web/src/ui/datefield.tsx) replace all nine
native controls — event editor (all-day and timed start/end, recurrence
until), out-of-office, contact birthday, advanced search. They take and emit
the same ISO strings the native inputs did, so call sites barely changed.
Each is a text box in the configured order plus a popover: a month grid
(week start from settings, locale weekday and month names, today and the
selection marked) and, for date-times, a list of times in the configured
clock. Keyboard: arrows move by day, PageUp/PageDown by month, Home/End
across the week, Enter picks, Escape closes, ArrowDown opens; the focused day
holds DOM focus so screen readers follow, and the dialog has an accessible
name (Popover gained an ariaLabel prop).
Text entry is lenient — the configured order with any separator, unseparated
digits (221125), day and month alone, non-Latin digits, and bare ISO always;
times take 18:23, 1823, 6:23pm, 930. What will not parse reverts on blur
rather than clearing the field, and impossible dates like 31 February are
rejected instead of rolling into March.
Editable boxes stay Gregorian and Latin-digit even where display does not
(fa-IR, th-TH, ar-EG): the locale's field order and separator are kept, but a
Buddhist-era year in a text box cannot round-trip against a Gregorian grid.
Noted in the README.
The out-of-office format echo added in #2 is gone — the fields now show the
right format themselves.
Closes#3
Every user-visible date now goes through web/src/lib/datetime.ts, driven by
three settings (Settings > General > Locale):
- Language & region: automatic, or any of the 618 locales CLDR has data for,
each named in its own language and script (web/src/lib/locales.ts, generated
by probing Intl over the subtag space).
- Date format: automatic (locale order), 22.11.2025, 22/11/2025, 11/22/2025,
or ISO 8601 2025-11-22.
- Time format: automatic (locale), 24-hour, or 12-hour.
Automatic takes the locale Stalwart has for the account, read best-effort at
login via x:Account/get (urn:stalwart:jmap) and passed to the client in the
session; servers without the capability, or that deny sysAccountGet to a
regular user, fall back to the browser locale. POSIX forms are normalised
(de_DE.UTF-8 -> de-DE) and script modifiers kept (sr_RS@latin -> sr-Latn-RS,
uz_UZ@cyrillic -> uz-Cyrl-UZ), while dialect/variant/currency modifiers are
dropped and a script the locale already implies is not appended.
Numerals follow the locale (22.11.2025 renders as Arabic-Indic digits under
ar-EG); ISO 8601 is the exception and pins date and clock to Latin digits so
one line never mixes digit systems.
Rewired: message list and headers, quoted reply headers, calendar (titles,
weekday and hour gutters, mini calendar, agenda, popovers, invite cards,
free/busy), contacts, files, sessions. No raw toLocale*String date calls are
left in web/src.
Native <input type="datetime-local"> pickers always follow the browser locale
and cannot be restyled by a page, so the out-of-office fields echo the entered
instant in the chosen format underneath.
Also: month-grid day labels no longer wrap when they hold a date, and the mock
server serves x:Account/get (MOCK_LOCALE, default en_US).
