The type of the pxOutcomeTime property in the
PR_DATA_IH_FACT table is by default set to DateTime. In the
Oracle database, any records that are written into the
PR_DATA_IH_FACT table of the interaction history are stored
with one-second precision.
In the Oracle database, records in the PR_DATA_IH_FACT table might
be displayed and stored at the same second because of the quick processing of customer
responses and the asynchronous execution of web page impressions.
