Question

So,
I’m storing a DateTime object as a private member on an object. This private member is set on object creation like so:

this.mCreateDate = DateTime.UtcNow.ToUniversalTime();

Now, later on in the application, I want to see how long the object has been alive for. This could be many weeks (this is a long running web app).

I’m getting the object lifetime like so:

DateTime now = DateTime.UtcNow.ToUniversalTime();

TimeSpan objectLifetime = now.Subtract(Foo.CreateDate);

// Output formatted time span

Does this all look correct?

Answer 1

First, calling ToUniversalTime() on DateTime.UtcNow is redundant, since .net 2.0, no conversion happens if the “Kind” of the source DateTime object is “Utc”.

Other than that, this looks fine.
