I have tried "YYYY-MM-DD HH:MI A"; "YYYY-MM-DD HH:MI"; "YYYY-MM-DD HH:MM A"; "YYYY-MM-DD HH:MM".
Some examples of the values in the timestamp columns are :
2021-02-13 12:00 AM
2021-01-06 5:45 PM
0000-00-00 00:00:00

For me ''YYYY-MM-DD HH12:MI AM'' is working on Snowflake.
But your 0000-00-00 00:00:00 will cause issues because this has not the same format and is no valid date/timestamp.
So you have to replace this value using a dummy or NULL.
One solution could be to import the data as string and do the calculation/casting afterwards.
Loading it as VARCHAR and then dealing with the values later is the best way to go.
