To create a replication definition for a table that contains a timestamp column, specify timestamp as the declared datatype for the column or use a column-level translation to specify timestamp as the published datatype for the column.
A replication definition, or multiple replication definitions for the same table, may not publish more than one column that has the datatype timestamp.
See Replication Server Reference Manual > Topics > Datatypes > Date/time, and Date and Time Datatypes.
