the entry by this location. By default, this should match the location of
the entry group containing this entry. A different value allows capturing
the source location for data external to Google Cloud.
The time when the resource was last updated in the source system. If the
entry exists in the system and its EntrySource has update_time
populated, further updates to the EntrySource of the entry must provide
incremental updates to its update_time.
