With this function you can set the maximum expire time that is
used by auth to a new value.
Parameter
integer
$time
expiration time,
number of seconds
boolean
$add
if TRUE$time
is added to the existing expiration time,
if FALSE the exitsing time value will be replaced.
Note
This function can not be called
statically.
Auth uses PHP's session mechanism
to recognize users between http calls.
Setting Auth's expiry time larger than the session timeout
will still expire the session to the time the php session
expires.
