hi,
i am one of the developers of iclock. we created a new installer that is better in many ways but when doing an install reported (incorrectly) that the version being installed was older then the version on your disk. it does not have any other problem. so we apologize for that but you can go ahead and use it just ignore that message.
as for the restart after installing. if you have a newer version of iclock then you can just quit the installer and you are fine. if you have an older version of iclock (pre 2.4) then we recommend a restart or logout. that is why we did it like that. we will try a different way of doing this in the next version. i know i certainly don't like restarting after intalling a new application.
a big thanks for all the good feedback.
