I posted what I think is a clever answer to:

[Excel Match Bug in a sparse range with duplicate keys](https://stackoverflow.com/questions/2362754/excel-match-bug-in-a-sparse-range-with-duplicate-keys/2581233)

But then I noticed the question was posted a while ago on Mar 2.

I wanted to see what the chance of the user logging back in and seeing my answer, but the [OP's profile](https://stackoverflow.com/users/205347/dangermouse) says the user was seen on Feb 19.

I thought this was supposed to be the date they last logged in? How could they have asked a question on Mar 2 if they haven't logged in since February?

Thanks
