From what I understand, for the lastmodified update method, Sqoop selects records where timestamp_column >= last modified timestamp and timestamp column < current_time. Is there a way to customize that current_time upper bound? Can I do something like current_time - 1 hour? 

We have transactions being created on one server, then replicated to another server, then Sqooped from there. I noticed some missing data in our cluster today, and suspect replication delay as the root cause.
