function getTimeRemaining(endtime) {
    const total = Date.parse(endtime) - Date.now();
    const seconds = Math.floor((total / 1000) % 60);
    const minutes = Math.floor((total / 1000 / 60) % 60);
    const hours = Math.floor((total / (1000 * 60 * 60)) % 24);
    const days = Math.floor(total / (1000 * 60 * 60 * 24));

    return {
        total,
        days,
        hours,
        minutes,
        seconds
    };
}

• Date.parse(endtime) converts the end time into a timestamp (in milliseconds).
• Date.now() gets the current time in milliseconds.
• We calculate the difference (total), then use that to extract the days, hours, minutes, and seconds.
• The function returns an object containing the remaining time.

• Each row (<tr>) contains three data cells (<td>), followed by an "Export" button that will trigger the export action.
• The button has a class of export-btn, which we will use to attach event listeners.

Now, we need to write the JavaScript code that will be responsible for generating and downloading the CSV file when the user clicks on the "Export" button.
