We have distance education courses that are, by some users, taken internationally. We feel it would be beneficial for cases like these where the server timezone is displayed somewhere on the portal.
One use case would be where a user is submitting an assignment from PST, but all the due dates are in EST. Also, setting aside different timezones, this could have a benefit just for the sake of showing the "official time" for users whose clocks may be +/- 5 - 10 minutes from the server.
Maybe there could be a property in sakai.properties 'portal.showservertime=true', and that would unlock the server time somewhere in the footer?
