[Bug]: error where tring to subscribe with timezone '+00:00' with iOS

[andreamattioli]

When Intl.DateTimeFormat().resolvedOptions().timeZone returns '+00:00' request to subscribe returns 400

Hard solution: fake timezone

(() => {
	try {
		if(Intl.DateTimeFormat().resolvedOptions().timeZone !== '+00:00') {
			return
		}
		const fakeTimeZone = 'Europe/Rome'
		
		const originalResolvedOptions = Intl.DateTimeFormat.prototype.resolvedOptions;

		Intl.DateTimeFormat.prototype.resolvedOptions = function() {
			const options = originalResolvedOptions.call(this);
			options.timeZone = fakeTimeZone
			return options;
		}
		console.log('Intl.timeZone faked as', Intl.DateTimeFormat().resolvedOptions().timeZone);
	} catch(e) {
		console.error('fakeTimeZone', e);
	}
})()

Hey @andreamattioli, apologies that this issue has gone stale. Does this issue still occur for you?

When trying to reproduce this issue I was not able to get Intl.DateTimeFormat().resolvedOptions().timeZone to return a timezone offset. I've tested this on Safari MacOS (as a control), iOS web, and iOS PWA; all shown below:

MacOS Safari

iOS Safari

iOS PWA

@andreamattioli on iPhone, I only saw the option to select UTC timezone and that doesn't error.

Hello, we'll be closing this as we can't really replicate it.
