У меня проблема таймер вкл работает неправильно он считает время перерыва никак не получаеться сделать так что-бы таймер не вкл время перерыва

function formatTime(seconds) {
    var minutes = Math.floor(seconds / 60);
    var remainingSeconds = seconds % 60;
    return minutes + ':' + (remainingSeconds < 10 ? '0' : '') + remainingSeconds;
}

function updateTimer() {
    var currentTime = document.getElementById('life-time').getAttribute('current-time');
    var startTime = document.getElementById('life-time').getAttribute('data-start-time');
    var pirodeAdd = parseInt(document.getElementById('life-time').getAttribute('data-periode-add')) || 0;

    var currentTimestamp = new Date('1970-01-01T' + currentTime + 'Z').getTime();
    var startTimestamp = new Date('1970-01-01T' + startTime + 'Z').getTime();
    var elapsedTime = Math.floor((currentTimestamp - startTimestamp) / 1000) + pirodeAdd;

    var pirodeTimeElements = document.querySelectorAll('[id="life-time"][data-periode-time]');
    var pauseTimeElements = document.querySelectorAll('[id="life-time"][data-pause-time]');
  
    for (var i = 0; i < pauseTimeElements.length; i++) {
        var element = pauseTimeElements[i];
        var pauseStartTime = element.getAttribute('data-pause-time-start');
        var pauseEndTime = element.getAttribute('data-pause-time-end');
        var pauseStartTimestamp = new Date('1970-01-01T' + pauseStartTime + 'Z').getTime();
        var pauseEndTimestamp = new Date('1970-01-01T' + pauseEndTime + 'Z').getTime();

        if (currentTimestamp >= pauseStartTimestamp && currentTimestamp <= pauseEndTimestamp) {
            elapsedTime -= parseInt(element.getAttribute('data-pause-time'));
            break;
        }
    }

    document.getElementById('life-time').innerText = formatTime(elapsedTime);
}

setInterval(updateTimer, 1000);
