How to record changes to cell values including time stamp

I have three columns in worksheet 1 (columns F, G, and H) that I want to record all changes to. If any value changes in those columns, I want it to record the previous value, the new value, and the time stamp it was changed. These recorded values/time stamps would be put into worksheet 2 (in columns B, C, and D respectively). The original values in worksheet 1 are alligned to a particular name (per row), so in column A on worksheet 2, it should say which name changed.

Hopefully this make sense. Any help would be much appreciated. Thanks.
