function formatDateTime(date) {

    const month = date.getMonth() + 1
    const day = date.getDate()
    const hour = date.getHours()
    const minute = date.getMinutes()
    const second = date.getSeconds()
    return `${pad(year, 4)}-${pad(month)}-${pad(day)} ${pad(hour)}:${pad(minute)}:${pad(second)}`
}

function pad(value, total = 2, str = '0') {
    return value.toString().padStart(total, str)
}
