date format is not recognized

Hello,

 

I have imported the attached file into rapidminer and I am trying to convert the attribute "click_time" to a date_time attribute. The format of the attributes is clearly yyyy-MM-dd HH:mm:ss, but when I try to convert it I get the error "Unparseable date: '2017-11-07 09:30:38'."

Hi,

 

how are you doing it?

It worked for me with your data in two ways: Directly in the Read CSV wizard or reading the date as nominal and using Nominal to Date.

Here's my process with both approaches. It works correctly on your data.
