JS get all date or time stamps between two time stamps

let start = new Date(1642694400000) // 2022-01-21 00:00:00
let end = new Date(1643644800000) // 2022-02-01 00:00:00
dateList = getAllDateCN(date1, date2)
console.log(dateList);

function getAllDateCN(startTime, endTime) {
    let date_all = [];
    let i = 0;
    while (endTime.getTime() - startTime.getTime() >= 0) {
        //  Get date and time 
        let year = startTime.getFullYear()
        let month = startTime.getMonth() + 1
        let day = startTime.getDate()
        let time = startTime.toLocaleTimeString()
        date_all[i] = year + ' year ' + month + ' month ' + day + ' Japan ' + time

        //  Get daily 00:00:00 The timestamp 
        // date_all[i] = new Date(startTime.toLocaleDateString()).getTime() / 1000;

        //  Days +1
        startTime.setDate(startTime.getDate() + 1);
        i += 1;
    }
    return date_all;
}
