stop importing the Time ontology
Affects: SAREF
Situation: the OWL Time ontology has an axiom that make it inconsistent. If SAREF imports it directly, then SAREF is inconsistent.
Proposal: do not import the OWL Time ontology, but add a section in the TS needs to explain to the user how this can be done
Status: agreed during SmartM2M-RG Meeting about 2 NWIs SAREFv3 and SAREF Com Framework V2 2019-04-08. SAREF4Indus and SAREF4Agri already propose mappings, they may be used as starting points
