Hi, is there such a work-around for make a subtraction between current datetime column and age column in order to get the birth datetime column as result?
Here below an example of what I mean:
age column -> 25
current datetime -> 2018-10-17
birth datetime ->1993-09-10
In this case of course we cannot be accurate for day and month, but at least for year we should be able to calculate it well.
Any suggestions? Thanks.
Hi there!
I would suggest to just subtract age column from current year. You can use Date&Time Shift node with Years for Granularity and your numerical column would be your age column. There is around <0.15% probability you will have accurate day and month 
Also there is still around 20% probability you will miss year as well

You might have a look at this example. With a little conversion you can determine the right age. This is KNIME style. You might also do such a thing with a Math node or a Java Snippet.
