I believe that if you provide the time as a field, it will be split up into
components (day of week, is weekend, etc.) and encoded as any ordinary
integer. So NuPIC won't treat this any differently than any other integer
field. The learning occurs online with every record, whether 10 minutes
have passed in the time field, or whether 1 hour has passed. Hope that
makes sense.
