How to Edit Start Date Time & End Date Time - times available on picklist


The fields 'start date time' & 'end date time'  have a drop down/picklist/ displaying all hours from 00:00 am - 23:45pm.
I want those field's picklist to only have hours available from 8:00 - 20:00pm, is this possible? if so how?

Hi, is not possible to restrict the input datetime picklist in a standard layout. 
Maybe you can put some description to the field and add a validation rule to prevent inserts from dates/ times that are not allowed.
