I'd argue that we need the 3 kinds of now() regardless, just to limit user
confusion. If we set things up as:
now() = transaction time
current_timestamp = statement time
timeofday() = exact time
That does give users access to all 3 timestamps, but using a competely
non-intuitive nomenclature. It's likely that the three types of now() would
just be pointers to other time functions, but would provide nomenative
clarity.
