What would you like to do?
ISO 8601 date string – like Date.prototype.toISOString(), but with local timezone offset
function getLocalISOString(date) {
const offset = date.getTimezoneOffset()
const offsetAbs = Math.abs(offset)
const isoString = new Date(date.getTime() - offset * 60 * 1000).toISOString()
return `${isoString.slice(0, -1)}${offset > 0 ? '-' : '+'}${String(Math.floor(offsetAbs / 60)).padStart(2, '0')}:${String(offsetAbs % 60).padStart(2, '0')}`
}
