This fix one issue, but default is still wrong IMHO:

When pressing RET with an empty prompt the value is different than what
is inserted in minibuffer with M-n.  Why do we bother setting the
timesamp at the exact time when pressing RET instead of when pressing
"T", I mean user would consider the timestamp is set once "T" is
pressed, with this the behavior would be consistent with RET and M-n and
the code much simpler.
