Safely comparing local and universal DateTimes

Question

I just noticed what seems like a ridiculous flaw with DateTime comparison.

DateTime d = DateTime.Now;
DateTime dUtc = d.ToUniversalTime();

d == dUtc; // false
d.Equals(dUtc); //false
DateTime.Compare(d, dUtc) == 0; // false

It appears that all comparison operations on DateTimes fail to do any type of smart conversion if one is DateTimeKind.Local and one is DateTimeKind.UTC. Is the a better way to reliably compare DateTimes aside from always converting both involved in the comparison to utc time?

Answer 1

To deal with this, I created my own DateTime object (let's call it SmartDateTime) that contains the DateTime and the TimeZone. I override all operators like == and Compare and convert to UTC before doing the comparison using the original DateTime operators.
