MD History: Round down timestamp used for incremental queries

MD History: Round down timestamp used for incremental queries

This ensures that results from incremental queries are strictly
older than existing results, while retaining millisecond accuracy.
This is equivelant behavior to the old History page, which rounds
down the timestamp using new Date().
