The Hidden Cost of DateTime.Now in .NET 🕰

You're Using DateTime.Now — and It's Breaking Your Code …
❌

Let's be honest: We've all written this:
if (DateTime.Now > token.Expiry)
{
return Unauthorized();
}


It works… until it doesn't.

In production, this little line can wreck your logic due to clock drift, time zone shifts, or mocking nightmares. 🐞
