I haven’t seen a method which would convert seconds in hours for you, if there really isn’t one, you’ll have to make the convertion to hours yourself… Cheers. ---

Neither do I… However, if you are using Rails and ok with requiring active\_support, that enables 1.hour for you. > but using 3600 instead should do the trick. In this case I’d vote for this option.

Hi Robert, the original code: (Time.now-incidents.first.created\_on).hours almost implies that it uses a framework like Rails so I naively blown these nn chars into this e-mail. Cheers Florian Am 27.11.2008 um 12:03 schrieb Robert D.:
