The entry for Chapman J. Tinsley in “Virginia, U.S., Wills and Probate Records, 1652-1900” indicates that the will was dated on the same date it was admitted to probate.
That’s not how it works. The will date is the date the will was signed by the testator. The probate date is the date it is admitted to probate by the judge of the court that handles probate matters in the relevant jurisdiction.
Other reminders here are to look at the original and to find the actual book in which the item is recorded–as Ancestry references several books for this item (without a page number either).
