Just read a headline saying scientists have created two dimensional time, what is this? What practical applications will it have?

Your question is vague so sorry if I’m not giving the answer you’re looking for. Posting the article may help.
The current mainstream model of the universe describes it as having one time dimension and three spatial dimensions. However you can come up with models that have any number of dimensions, for instance F Theory describes it as 12D universe with two time dimensions (with kind of an asterisk but that’s beyond the point). These are very mathematical theories and one consequence of whatever set of equations they’re using is that you have to change the amount of dimensions they’re operating on to have them continue to describe how things move in the real world.
