Nogenlunde fornuftigt, jeg tog for god ordens skyld også tidspunkt med da det næppe vil give noget særligt arbejde, heller ikke serverside !-)
Bemærk i øvrigt, at jeg også bruger et timestamp, Now i updated-variablen, som bruges til at udligne forskellen mellem servertiden og den lokale browsertid:

-- da datoformatet er låst, skal du altså lave tidspunkterne serverside i formatet: dd-mm-åååå tt:mm:ss !o]
