Yes exactly like current code, see below.

What I see and is wrong IMO is:

- DEFAULT is the timestamp of the current file at point and prompt says
that DEFAULT is "now".

- Pressing RET should use DEFAULT, but IIUC what you say, it returns
current-time timestamp, is it correct?
If so this is another inconsistency, RET should always return DEFAULT with an
empty prompt.
