Getting a list of issues from Github closed within date range using Octokit

example.cs

var credentials = new Credentials(login, password);

var credentialStore = new InMemoryCredentialStore(credentials);
var productHeaderValue = new ProductHeaderValue("MyAmazingApp");
var connection = new Connection(productHeaderValue, credentialStore);
var apiConnection = new ApiConnection(connection);

var issues = new IssuesClient(apiConnection);

var closedSince1Point2 = issues.GetForRepository("ownerLogin", "repoName", new RepositoryIssueRequest()
    {
        State = ItemState.Closed,
        Since = new DateTimeOffset(new DateTime(2011, 4, 3, 14, 0, 0)),
        SortDirection = SortDirection.Descending,
        SortProperty = IssueSort.Created
    }).Result.Where(x => x.ClosedAt < DateTime.SpecifyKind(new DateTime(2012, 6, 20), DateTimeKind.Utc)).OrderBy(x => x.CreatedAt);
