"last timestamp" here refers to the date in previous item or last date
class was held?

The reference to spreadsheet like formula suggests that you want the
date from previous item to be used to calculate the date for current
item and a change in the former should cause an appropriate change on
the latter. org-depend.el (in contrib/lisp) can be used to define the
relationships but I don't know how you could link dates that way.

Not very helpful.  Sorry.
