Compared with variable instance on heap, generally speaking why operations on stack is better?

It probably is a waste but you need an instance of the DateTime struct to exist to be able to get the value!

the Now property is static, so there is no instance existing before calling the property

public struct ExampleDateTime
{
    private int mSomeValue;
    public int SomeValue
    {
        get { return mSomeValue; }
    }
    public static void Now(out ExampleDateTime outParameter)
    {
        outParameter.mSomeValue = 1;
    }
}

ExampleDateTime example = new ExampleDateTime();
ExampleDateTime.Now(out example);

there are two DateTimes, the nowDateTime and the one returned and copied from DateTime.Now.

static void Test2(out DateTime abcd)
{
    abcd = DateTime.Now;
}

static void Main(string[] args)
{
    DateTime abcd;

    Test2(abcd);

    return;

In DateTime nowDateTime = DateTime.Now; there are two DateTimes, the nowDateTime and the one returned and copied from DateTime.Now.
