Error using date type for Stream Learning

[Nida Meddouri]

Hello

I'm trying to do stream learning from attack data with a date attribute.

I get my data in arff format (no problem to evaluate them with weka).

But when I try to use MOA, I get this message:

Failure reason: For input string: "2021-04-09 18:23:28"

*** STACK TRACE ***java.lang.NumberFormatException: For input string: "2021-04-09 18:23:28"

Have you an idea about this error ?

Greatly looking forward to hearing from you soon.
