Comparing COleDateTime Objects

The first 5 years of my career I programmed in pure C. (Production automatisation software)
In Q4 of 1997 I switched to Visual C++/MFC. (Headend Management system for cable operators)
In Q1 of 2003 I changed job and started programming in JAVA (and Swing)
Later on I also worked in Adobe Flex, GWT and GXT.
Then, since our products became more web based, I started programming in JavaScript and Sencha ExtJS.
In my current job I program in Java, TypeScript and React.
