Incorrect Time Stamp In History Properties

Hi,

I need help with a basic issue I have with the time stamp / last viewed
under the properties in my history field. If I return to my history to
confirm when a site etc was last viewed to open the properties for that
information, I receive the present/current time instead of when I actually
was there. This has happened on two other computers I use to share, and
have been told that no one knows why this has happened. For my part, I have
not learned basic opertions of computers other than how to access what I
want. I am learning fast that leaving that privelege and rights to everyone
else is not wise. I am reading the owners manual and am reading it to learn
the absolute basics but I would like to know how I can change the time to
provide the correct information.
