Parameters
- source
- DbSet<TEntity>
Source DbSet on which the temporal operation is applied.
- utcFrom
- DateTime
Point in time representing the start of the period for which results should be returned.
- utcTo
- DateTime

Returns
An IQueryable<T> representing the entities present in a given time range.
Remarks
Elements that were created at the starting point as well as elements that were removed at the end point are included in the results.
All versions of entities in that were present within the time range are returned, so it is possible to return multiple entities with the same key.
