date format

[piotro21]

Hi, could you consider other date/time formats? My system, and firefox for that matter, use the ISO YYYY-MM-DD format, but the Tooltip displays DD.MM.YYYY instead.
Many thanks for the extension 👍

The code uses toLocaleDateString and toLocaleTimeString to format the date and time::

const originDate = new Date(originTimestamp);
return `${originDate.toLocaleDateString()} ${originDate.toLocaleTimeString()}`;

Both these functions are based on the browser's default language / locale:

The toLocaleDateString() method returns a string with a language sensitive representation of the date portion of the specified date in the user agent's timezone.

The toLocaleTimeString() method returns a string with a language-sensitive representation of the time portion of the date.

The date the extension shows in the tooltip uses a short date format for the browser's default locale. It's possible to change it to a long format, but that will be even more dependent on the current language / locale and I'm not sure it would be preferable. Here's an example of long date formatting, from MDN:

const event = new Date(Date.UTC(2012, 11, 20, 3, 0, 0));
const options = { weekday: 'long', year: 'numeric', month: 'long', day: 'numeric' };

console.log(event.toLocaleDateString('de-DE', options));
// expected output (varies according to local timezone): Donnerstag, 20. Dezember 2012

console.log(event.toLocaleDateString('ar-EG', options));
// expected output (varies according to local timezone): الخميس، ٢٠ ديسمبر، ٢٠١٢

Anyway, it's a simple extension I wrote years ago. I'm not really interested or motivated to put the time and work to add configuration options to it (which would include a dedicated settings page, storage and synchronization code, requesting further permissions, etc.). I don't feel it would be worth the effort.
