 |January 1, 0 || Symbian and Turbo DB, MATLAB || 

 Symbian appears to be effectively defunct, which makes it hard to obtain information about it. I was not able to locate any documentation that seemed likely to address the epoch. 

 "Turbo DB" is difficult to identify. A web search returns results for seemingly different products. 

 MATLAB has a few different ways to represent dates. http://www.mathworks.com/help/matlab/ref/datenum.html states "The datenum function creates a numeric array that represents each point in time as the number of days from January 0, 0000. The numeric values also can represent elapsed time in units of days. However, the best way to represent points in time is by using the datetime data type." This seems to contradict the information in the article, and also makes it doubtful whether a date associated with the datenum function should be mentioned in the article when MathWorks seems to consider the datetime data type superior.
