As the title says, The chapter 15, section 4 part of the comprehensive review lab is asking the student to change the time zone on the system:
Setting / changing time zones used to be part of chapter 9 of RH124. It has since been moved into the RH134 class (chapter 3).
It seems like there might be some issues with version control processes internally.
I am seeing changes to courses but suplimentary materials (ex, instructor manuals) do not reflect these changes.
I can't emphasis in words how much I appreciate the materials and systems we are provided, but something like this is pretty crucial.
