If all student-led clubs are required to meet after school it is legal.
The school/staff-led groups (that I assume have nothing to do with religion) are completely different.
They are different simply because they are organized by the state, in this case, the school itself. The fact that all clubs may have a faculty advisor doesn't come into play.
A school is well within its' right to say school-sponsored clubs can meet during school hours and others aren't.
