Save dates on documents in Corel x7

I create a document on say 18 Jan 2016 revisit the document on say 1 Feb 2016, When I save the document it shows as the creation date of 18 Jan 2016. If I resave the dumnt it shows the document date as 18 Jan 2016. This is very annoying as when yoyu want to go to the latest version or visit a file as per date it is unclear which was the latest date you were working on the document/project. Is there some magical setting involved here??
