date format and date_add
Hello,
I have a problem with a macro with the name time_frame. Its value is set on 27/07/2015 1:00:00 AM
In a loop I want to increase this marco with each loop by 5 Minutes. I tried: date_add(%{time_frame},5,DATE_UNIT_DAY), but that doesnt work.
The failure message is: Invalid argument type for 'date_add'. first argument must be Calendar
So the question is, where is the mistake?
Thank you in advance,
Samuel

the first argument needs to be of type date. This means it needs to be in rapidminer date (milliseconds since 1970). You can use the parsing functions to convert your date into a RM date.
