When I use (get-buffer-create " Time Sched ") with a buffer name that 
begins with a space, Emacs treats it as a special (internal) buffer. 
As a result, this buffer will not appear in the Buffers List or the 
menubar.

The buffer will be hidden from the standard buffer selection interfaces.

See (info "(emacs) List Buffers"):

     By default, ‘list-buffers’ omits buffers whose names begin with a
  space, unless they visit files: such buffers are used internally by
  Emacs (but the ‘I’ command countermands that, *note Several Buffers::).
