Special Icon on System-Versioned Table in SQL Server 2016 – Interview Question of the Week #101

Question: I just installed SQL Server 2016 developer version and new samples database WideWorldImports, upon expanding the tables, I noticed a special icon on the System-Versioned table which looks like a watch. What does this special icon which looks like a watch represents in SQL Server Management Studio 2016?

Answer: Honestly, this was not asked in any interview questions, but I made it up myself. More than an interview question, this is fun trivia which we all would love to learn.

Before we answer the question, let us see an image which displays the icon which we are talking about.
