today.setHours(0, 0, 0, 0);
todayMillis = today.getTime();

data.forEach(d => {
    var parts = d.time.split(/:/);
    var timePeriodMillis = (parseInt(parts[0], 10) * 60 * 60 * 1000) +
                           (parseInt(parts[1], 10) * 60 * 1000) + 
                           (parseInt(parts[2], 10) * 1000);

    d.time = new Date();
    d.time.setTime(todayMillis + timePeriodMillis);
