No Im not a current JW
But anyway the JWs official belief has not changed ,that is a creative day is 7000 years,they dont talk much in more recent literature about it and if you asked most witnesses they would fudge the issue by saying the creative days were not literal days but very long periods of time,they have never recounted on their Fred Franze era teaching that the creative days are equal periods of 7000 years,and that we are now near the end of the last day,the rest day,which would end at the end of the 1000 year reign.
I dont think that the watchtower mentions this definition now because that would put the start of the creative days as about 48000 years ago and the realm of mammals like dinasours much more recent still which is would not wash well with educated people.
