Formula To Add Year and Format Change

Hi,

I have a column with a date/time format that is showing for example 11.12 02:37. This comes from a software I am using.
In another column I would like to it show as 11/12/19 02:37. I have tried using the formula =date(YEAR(A2)+19,MONTH(A2),DAY(A2)) but it did not work.

Does anyone have a solution for this?

Thanks in advance,

Aarron
