I've not read this entire article but there does seem to be a problem... for example, this is a quote from the article...
When I ran the code in Listing 6, it produced the results found in 1.
Figure 1: Results when executing code in Listing 1
By reviewing the results in Figure 1, you can see that the current date/time was displayed as a DATETIME data type value.
The thing is, there is no "Figure 1" in the article.
