Converting time stamps in excel to dates

Question

I have a very large excel spread sheet that has a column of time stamps. Does anyone know convert that over to a date? Is there a function I can use? I tried format cell dat

The answer of @NeplatnyUdaj is right but consider that Excel want the function name in the set language, in my case German. Then you need to use "DATUM" instead of "DATE":

=(((COLUMN_ID_HERE/60)/60)/24)+DATUM(1970,1,1)
