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

Answer 1

=(((A1/60)/60)/24)+DATE(1970,1,1)+(-5/24)

assuming A1 is the cell where your time stamp is located and dont forget to adjust to account for the time zone you are in (5 assuming you are on EST)
