…stamp (#381)

* changing "this interaction ends in 30 mins" to timestamp

* adding the imports to make the code work

* handling the timestamp logic with format_dt

* removing the variable self.end_time

* testing to see if this solves the conflict, will revert if not

* reverting changes

* small syntax error fix
