      Description

      Dear Alex,

      Glad to hear you are using the CEP!

      What you can do:
      1. Have one EPA, lets call it EPA1, that uses the temporal context you
      defined, lets call it TC1, (initiator Event_X, terminated after 24 hours).
      Make EPA1 of type Aggregate, that uses TC1. Set the evaluation policy of
      EPA1 to be deferred and don't set it conditions or input event. Make it
      generate a new type of event (that you need to define), lets call it E2.
      The purpose of EPA1 is to generate E2 24 hours after Event_X arrives. (If
      you don't want to have a warning on empty input events you can put Event_X
      as an input event of EPA1)

      2. Now you can define another temporal context, lets call it TC2 that uses
      E2 as initiator.

      Hope this is what you wanted.

      I cc the FIWARE help, so this corresponding will be documented in the
      FIWARE issue tracking system. Please cc it as well in future
      correspondence. Thanks.

      Best regards,

      Subject: Complex Event Processing, help

      Dear Tali,

      I am a Software Engineer who collaborates with the FiWARE GE,
      I am working on the IBM Proton about 2 weeks now, and I ma trying to
      configure a use case for the company I work for.
      I created a temporal context that starts the time that an Event_X is fired
      and it expires after 24hours, but I want a second temporal context start
      after 24hours of the event creation, can you please provide me some help
      on this?
      I tried to set the condition: Event_x.duration == 86400000, but that
      didn't work for me.

      Thanks in advance!
      Alex Zacharopoulos, Software Engineer @ Konnektid.
