Problem with displacement-time data extraction for a transient structural analys

      Greetings, this is shivam. I am a graduate student and I am stuck in a problem with ANSYS MAPDL for quite some time now. 
      I was performing a transient analysis wherein I defined 2 load steps. The time at the end of the first load step was 2 seconds and the time at the end of the second load step was 2.0001 seconds. This was specified using the "time" command. The problem is that I want displacement data as a list for all the substeps defined. From 0 to 2 seconds I can get that data but from 2 to 2.0001 seconds there is a problem. The displacement vs time list at the node of concern gives the time values as 2.000, 2.000, 2.000 as so on and at the end it is 2.0001. I want to tell that for the second load step I defined 700 substeps which means my time values in the list should go on like 2.000000142, 2.000000285 and so on. So that I will be able to plot it on excel. 
       
      Please help me, I am stuck with this for quite some time now. It will be much appreciated.

      If this output is created with the prvar command in post26 then the /format command can help.   For example, /format,,F,20,16 produces time values like below for your case.
