I was just pointing out that there might be a difference between the two
cases. If you don't care about rounding, you can just use current_timestamp
instead of current_timestamp(0).

What would it be rounded to, for the sake of knowledge?

I will change all my table defintions to timestamp(0). BTW, what is the default resolution? I'm am
in the process of RTFM'ing, don't worry.
