Special note, I found no real appreciable difference between the following:

select * into #Test2 from dbo.fn_GetTimestampRangeRCTE ('2006-01-01','2006-02-01', 0) OPTION (MAXRECURSION 0);

select * into #Test2 from dbo.fn_GetTimestampRangeRCTE ('2006-01-01','2006-02-01', 0) OPTION (MAXRECURSION 60);
