I managed to go from timestamp to date with <dtml-var "ZopeTime(967322055)" fmt="%H:%M"> But how do convert a date to timestamp? I.e. from say: "27/08/00 23:59" to 967322xxx? All I know to begin with is the day, month and year. Would be nice if I can do this in DTML straight away. Is it time.mktime something?
