Temporal concept

const getTemporal = () => {
	if (!('Temporal' in window)) {
		return
	}
	try {
		const inParentheses = /\[(.+)\]/
		const inBrackets = /\<(.+)\>/
		const { now } = Temporal
		const zonedDateTimeISO = now.zonedDateTimeISO()._repr_
		const timeZone = now.timeZone()._repr_
		const tz1 = (
			inParentheses.test(zonedDateTimeISO) ?
			zonedDateTimeISO.match(inParentheses)[1] :
			undefined
		)
		const tz2 = (
			inBrackets.test(timeZone) ?
			timeZone.match(inBrackets)[1] :
			undefined
		)
		return tz1 === tz2 ? tz1 : undefined
	}
	catch (error) {
		console.error(error)
		return
	}
}
