iceweasle history search by specific time

[lina <lina.lastname@gmail.com>]

Hi,

I know sometimes I looked through a website, let's say Saturday
07,May,2011 02:47:36 PM SG

actually it's something I downloaded, but I failed to find the exact
URL. and the history list is so long.

How can I find the specific url of that time,

Thanks,
