OK, so I have a model that contains 2 records, among others startdate :time enddate :time I have one set of values in the database 20:00:00 for startdate and the same for enddate However, I have no clue how to add 90 minutes to enddate, relative to startdate. Event though the datase has 20:00:00 only, I get inside my view something like Sun May 17 18:00:00 +0300 2009 and I cannot get it to add 90 minutes to display Sun May 17 19:30:00 +0300 2009 I tried with advance method, but only :days, :years etc works… :hours, :minutes don’t change anything… ---
