org-clocktable-shift

org-clocktable-shift is an autoloaded Lisp function in `org-clock.el'.

(org-clocktable-shift DIR N)

Try to shift the :block date of the clocktable at point.
Point must be in the #+BEGIN: line of a clocktable, or this function
will throw an error.
DIR is a direction, a symbol `left', `right', `up', or `down'.
Both `left' and `down' shift the block toward the past, `up' and `right'
push it toward the future.
N is the number of shift steps to take. The size of the step depends on
the currently selected interval size.
