Kibana do not recognize the unix timestamp field in elasticsearch

Hi , i index the data to es with a date field that with the "strict_date_optional_time || epoch_milis" format, then i config the index in kibana use that date field as Time-field. But when i discover the index in kibana, there is no result found.

sorry, i got my mistake. The time field id stored with the type epoch_second, i think i must to reindex and solve it
