Lesson Availability options Open Date

In the field "Open Date" (The date this Lesson will become available) I have set it to "May 30 2017". There no way to set the open time. But when users go to the test they see "Opens 05/29/2017 - 17:00" There is a time but it is the date is now the day before. In the Site configuration admin/config/regional/settings Default time zone is set to America/Los Angeles -0700 which is the same setting as the server (and ALL my students are in this time zone). How can I set Lesson open date to open on the day I want and not the evening before. Same problem with the Close date
