CSV From Oracle with timestamp column getting errors

[Saha, Sushanta K]

\COPY table1 FROM '/tmp/Oracle_2020_06.csv' DELIMITER ',' CSV HEADER;
ERROR:  invalid input syntax for type timestamp: "01-JUN-20 06.04.20.634000
AM"
CONTEXT:  COPY table1, line 2, column last_update_timestamp: "01-JUN-20

Appreciate any help with this psql command.
