"console core:delete-logs-data" does not consider the time difference from GMT

The following log is imported.

Then I ran the following command.

console core:delete-logs-data --dates=2015/01/06,2015/01/07
console core:invalidate-report-data --dates=2015-01-06

As a result, following data remains in the visitor log.
