  1. Bro, how to format date-time with the milisecond, for ex.:
    2014-12-09 17:40:36.973

    “973″ .. milisecond..


    • Hi,

      I think, this cannot be created using format. But there is a solution. Import date-time value as a text in A1 and write the formula =RIGHT(A1,3)&” milliseconds” in the some other cell. It will show the last 3 characters from the text and joins the units.
