Version:            (using KDE 4.1.2)

There could be created next clock (Plasma is all about clocks ;-)), that allows for fully custom date formatting using for example a strftime function, like in IceWM. This maybe could use Webkit to allow for use of CSS for advanced font formatting and inserting line breaks etc. User should have possibility to set refreshing rate (second, minute, hour etc.) or it could be detected once by checking for used date placeholders.
