Invalid date when changing timezone

[ablanco]

Describe the bug
I'm getting an Invalid Date error when changing the timezone with dayjs.

It is related to the src/plugin/timezone/index.js file, line 98 and 99.

const target = date.toLocaleString('en-US', { timeZone: timezone })
const diff = Math.round((date - new Date(target)) / 1000 / 60)

new Date doesn't work with the output of toLocaleString, so that conversion doesn't work. For example:

const date = Date(2022, 3, 20);
date.toLocaleString("en-US", { timeZone: "Europe/Madrid" });
// This outputs: '4/20/2022, 12:00:00 AM'
new Date('4/20/2022, 12:00:00 AM');
// This returns an Invalid Date

This makes this code to return an Invalid Date:

dayjs(`${date} ${time}`).tz('Europe/Madrid').format('MMM D, YYYY - HH:mm');

Expected behavior
I expected the method tz to return a valid dayjs object in the requested timezone.

Information

• Day.js Version 1.11.6
• OS: ArchLinux
• Browser Chrome 107 (also in Node 19.0.1)
• Time zone: GMT+01:00 CEST
