ok here you go, takes the 2 arguments specified in the comments, and assumes a reasonable version of js is running.

function getticks(starttime, count) {
    let ticks = [],
        date = starttime;
    for (let x = 0; x < count; x++) {
        let hours = date.gethours().tostring(),
            mins = date.getminutes().tostring(),
            seconds = date.getseconds().tostring();

        date = new date(date.gettime() + 60000);
        ticks.push(`${hours.padstart(2, '0')}:${mins.padstart(2, '0')}:${seconds.padstart(2, '0')}`);
    }

    return ticks;
}
