If you search for questions posted on time `1296897085` or later (by specifying `sort=creation` and `min=1296897085`), it may still return questions posted before that date:

http://api.stackoverflow.com/1.0/search?tagged=java;algorithm&sort=creation&min=1296897085&pagesize=2

In this case, it returns a question posted one second before (`1296897084`). But the gap can be more: e.g. specifying min date as `1296897100` still gives that question, but `1296898100` does not.

So, `min` seems to be 'inexact' restriction.

This is not a stopper bug, as I can filter returned questions manually, but I thought it's still worth reporting.
