Try to read the rule as follow:
One date! then 2 blocks.
That blocks should have one string! and then one time! value.
"copy items 2" is not a correct separation.
To make it clear, read it as:
(date!) (copy items) (2 into [string! time!])

There's no document about "2 into block!" except
"into block!", isn't it?

In core.pdf file there is a section named Parsing Sub Blocks on page 452. You can find information about "into" there.
