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. 

    <?xml version="1.0" encoding="UTF-8"?><process version="7.6.003">
    <context>
    <input/>
    <output/>
    <macros/>
    </context>
    <operator activated="true" class="process" compatibility="7.6.003" expanded="true" name="Process">
    <process expanded="true">
    <operator activated="true" class="read_csv" compatibility="7.6.003" expanded="true" height="68" name="Read CSV" width="90" x="112" y="34">

    <parameter key="column_separators" value=","/>
    <parameter key="date_format" value="yyyy-MM-dd hh:mm:ss"/>
    <parameter key="first_row_as_names" value="false"/>
    <list key="annotations">

    </list>
    <parameter key="encoding" value="UTF-16"/>
    <list key="data_set_meta_data_information">

    </operator>

    <parameter key="6" value="attributed_time.true.attribute_value.attribute"/>
    <parameter key="7" value="is_attributed.true.integer.attribute"/>
    </list>
    </operator>
    <operator activated="true" class="nominal_to_date" compatibility="7.6.003" expanded="true" height="82" name="Nominal to Date" width="90" x="246" y="136">

    </process>
    </operator>
    </process>

    Regards,

    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
