Problem with json deserialization

I have an issue with deserialization of the datetime from a JSON string. I need to deserialize 2024-07-09T10:36:23:000Z into a datetime object, but currently, I am having a problem with deserialization. My code looks like this:

using System;
using System.Text.Json;

string jsonString = "{\"Date\":\"2024-07-09T10:36:23:000Z\",\"Message\":\"Hello, World!\"}";

MyData? data = JsonSerializer.Deserialize<MyData>(jsonString);

Console.WriteLine(data.Date);  // Output: 7/9/2024 10:36:23 AM

public class MyData
{
    public DateTime Date { get; set; }
    public string Message { get; set; }
}

using System;
using System.Text.Json;

string jsonString = "{\"Date\":\"2024-07-09T10:36:23:000Z\",\"Message\":\"Hello, World!\"}";

MyData? data = JsonSerializer.Deserialize<MyData>(jsonString);

Console.WriteLine(data.Date);  // Output: 7/9/2024 10:36:23 AM

public class MyData
{
    public DateTime Date { get; set; }
    public string Message { get; set; }
}

With this error

System.Text.Json.JsonException: The JSON value could not be converted to System.DateTime. Path: $.Date | LineNumber: 0 | BytePositionInLine: 34.
 ---> System.FormatException: The JSON value is not in a supported DateTime format.

System.Text.Json.JsonException: The JSON value could not be converted to System.DateTime. Path: $.Date | LineNumber: 0 | BytePositionInLine: 34.
 ---> System.FormatException: The JSON value is not in a supported DateTime format.

Shoud be problem in culture setting in os? Or how can I serialize it without creating a new converter?

❔ Laptop Battery Info

I would like to create a simple app that monitors information about the battery, such as its overall health, capacity, voltage, and other relevant details. Currently, I have create a basic console app in .NET Core that retrieves some information about the battery. Here's the existing code:

using System;
using System.Management;

class Program
{
    static void Main()
    {
        ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_Battery");

        foreach (ManagementObject queryObj in searcher.Get())
        {
            PropertyDataCollection properties = queryObj.Properties;

            foreach (PropertyData property in properties)
            {
                Console.WriteLine($"{property.Name}: {property.Value}");
            }
        }
    }
}

using System;
using System.Management;

class Program
{
    static void Main()
    {
        ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_Battery");

        foreach (ManagementObject queryObj in searcher.Get())
        {
            PropertyDataCollection properties = queryObj.Properties;

            foreach (PropertyData property in properties)
            {
                Console.WriteLine($"{property.Name}: {property.Value}");
            }
        }
    }
}

However, this code does not provide all the desired information about the battery. I need to retrieve additional details like the current battery capacity and designed battery capacity. How can I modify the code to obtain these missing or additional battery information? Here's the sample output from the current code:
