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