more time filtering options in the class page

now obviously this would seem like a bad sleep schedule to most people but it should at least be an OPTION to look at the time between 10PM and 7AM.

also maybe the ability to filter between specific times like selecting just 5PM, for if somebody only has one or two openings in their day and they don’t want to look through all 50 classes in the evening to find out they only actually have 3 choices.
