New last.fm feature

Looks like last.fm can predict future listening:

Of course this is really just a time calculation bug, the music listed itself properly represents my recent past listening. What amazes me, though, is the smoothness of this bug from a user interface perspective. It does not look like a bug at all. It does not say: »-1 minute ago,« or anything obviously faulty. It rather appears as if the Web site calmly and confidently states a fact that it knows is true and accurate. Only that it isn’t.

I reckon that behind the scenes some generic library function does a good job of translating time stamps into natural-language relative descriptions such as those that we see above. This seems like a good thing in general, but we should use this opportunity to remind ourselves that bugs may not always look like bugs.
