      IE is sensitive to the server side time,  firefox seems to offset
from client time (or at least a minimum amount of cookie would be in the
past).  Anytime you hear that a cookie issue exists on IE but not firefox
your first suspect should be the server time.  This can be a big issue on
virtualized servers (vmware) that do not have the proper time config on
them for the host (or a OS that does not respect the types of time updates
that vmware is pushing out).  I have seen poorly configured hosts drift as
much as 3 hours per hour on vmware.
