Sea Breeze:
You may be technically right, but I think with their latest comments they are leaving open the possibility of millions and billions of years of creation time periods (days) for plants and animals.
It is certainly
possible, and it is in their interests to be generally vague in view of undeniable science on the matter, as well as a desire to distance themselves from other 'creationists'.
However, their end-times beliefs also require that 'God's day of rest' - the 7th 'day' of the 'creative week' - is a relatively short period of time, which implicitly restricts the length of the other 'creative days'.
They have also made statements since 2010 that continue to refer to the 'creative days' as only thousands of years.
Awake!, January 2014, page 12:
Evidently, these “days” of creation lasted many thousands of years.
Awake!, March 2014, page 5:
• In the Bible account, each of the six creative days could have lasted for thousands of years.
Insight (2018 revision), volume 1, page 919:
After Genesis 1:1, 2 (relating to the creation of the heavens and the earth), the book evidently covers a span of thousands of years involved in the preparation of the earth for human habitation
The only exception is that the entries for Creation and Day in the latest printing of Insight say the duration of the 'creative days' was "at least thousands of years" (formatting added).
The only certainty at this point is they will continue to be vague about it.
