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.

Your process worked for me, even though I tried both of these options before. I must have messed up some of the settings (my encoding was set to SYSTEM and not UTF-16, maybe that is why). 

 

Thank you for your help
