You can change the field length in the outbound variant so that the field will become truncated after the COPY (I am not sure what happens if you use a PATHCOPY).
That can be a problem if you are sharing the vatiant and other systems want the time. We don’t share variants here so that is not an issue.
The other option is to us a Tcl proc to truncate the field.
