Andrew, The database never tried to guess what precision was intended. Unless explicitly specified at write time via the "precision" query string parameter <http://docs.influxdata.com/influxdb/v1.0/tools/api/#query-string-parameters-1>, all timestamps are always interpreted as nanoseconds. If the precision parameter is set, InfluxDB interprets all timestamps in the batch to be at that precision.
If the timestamp is 1476810813 and "precision=s" then the database will record that point at about 21:15 on October 18th, 2016. If the timestamp is 1476810813 and precision is missing or set to "ns", then the database will record that point at 1.5 seconds after midnight, Janurary 1st, 1970.
