Please let me know the details of fitbit devices data recording period.
I read the article "How do Fitbit devices sync their data?", and know the fitbit device keep detailed records for 7 days.
When I start using fitbit device from "2018/01/01 06:10", which one is the correct recording period?
(A) from "2018/01/01 00:00" to "2018/01/08 00:00"
(B) from "2018/01/01 06:10" to "2018/01/08 06:10"
