Preferences
How the product renders for you. These apply everywhere you sign in, and change nothing for anyone else — a colleague reading the same test run sees the same instant written their own way.
The preview tells you what you are choosing
A panel headed Dates and times sits above the three controls, showing the current date and time written exactly as the settings below it would write it — for example 09/10/2026 at 3:21 PM. Underneath, it names the timezone in force: “How every date and time in the product appears to you, in (UTC+01:00) Europe/London.”
The preview updates as you change any of the three settings, before you save. It is the fastest way to tell MM/DD/YYYY from DD/MM/YYYY without doing arithmetic in your head.
Timezone
The timezone picker lists every zone with its current UTC offset — (UTC+09:00) Asia/Tokyo — and opens with a Search box, so typing a city name is faster than scrolling.
Until you save one, the timezone is a guess. A new account has no timezone of its own, so the page falls back to the one your browser reports and says so: “Guessed from this browser and not saved yet, so it can change on another machine. Saving fixes it to your account.” The guess belongs to the browser, not to your account, which is what the note means by another machine. Pressing Save changes once removes the note — from then on the zone travels with your account.
Date format
Used everywhere a date is written out. Three choices:
MM/DD/YYYYDD/MM/YYYYYYYY-MM-DD
Time format
The clock style for times of day. Each option shows itself rather than describing itself:
- 12-hour —
1:05 PM - 24-hour —
13:05
Saving
All three settings share one save bar. Change any of them and it reads Unsaved changes; Discard restores all three at once and Save changes writes them together, confirming with Preferences saved. Nothing is written before that, which is why you can try three date formats against the preview and walk away having changed nothing.
