I need to automaticly execute a zopescript once a day (e.g. "ZopeTime().strftime('%H')==00") determined by the system clock. Any ideas how this can be accomplished within zope? Can I use zope-time as a referrense to the system clock or do I need to go via python? Have never done it before myself so any tests, code bits etc required are of great help. Cheers, Espen
