当我在django模板中格式化时间时，为什么我的时间倒计时返回NaN

from django.shortcuts import render
from datetime import datetime

def my_view(request):
    current_time = datetime.now()
    end_time = datetime(2023, 10, 1, 0, 0, 0)  # 示例结束时间
    context = {
        'current_time': current_time,
        'end_time': end_time,
    }
    return render(request, 'my_template.html', context)

from django.utils import timezone

def my_view(request):
    current_time = timezone.now()
    end_time = timezone.make_aware(datetime(2023, 10, 1, 0, 0, 0), timezone.get_current_timezone())
    context = {
        'current_time': current_time,
        'end_time': end_time,
    }
    return render(request, 'my_template.html', context)

<!-- my_template.html -->
<p>Time remaining: {{ end_time|timeuntil:current_time }}</p>

<!-- my_template.html -->
<script>
    document.addEventListener("DOMContentLoaded", function() {
        var current_time = new Date("{{ current_time|date:'Y-m-d H:i:s' }}");
        var end_time = new Date("{{ end_time|date:'Y-m-d H:i:s' }}");
        var time_remaining = end_time - current_time;
        if (isNaN(time_remaining)) {
            document.getElementById("time_remaining").innerText = "Invalid time";
        } else {
            document.getElementById("time_remaining").innerText = time_remaining + " milliseconds";
        }
    });
</script>
<p id="time_remaining">Loading...</p>
