Manipulating Timestamp

Created: Mar 6, 2023 04:23 AM  |  Last Modified: Jun 8, 2023 9:31 AM (3460 views)

Hi I am struggling to convert a Timestamp into numeric format. I basically want to use the timestamp to create an Elapsed Time column. I am having difficultly achieving this with JMP16. Below is an example of the format. The change from 12:59 to 01:00 also seems to cause issues for me.

I was able to work with excel and manipulate the data to give me an Elapsed time in minutes (from row 1 as starting point). But I would prefer to use JMP and to create a script for it.

 

Thanks

I am not seeing the error.  See the display below.  I have also attached my data table.  The Time 2 column is the same values as the time column, but with the display format set to display the actual numeric data values behind the date/time.  It is the number of seconds since January 1, 1904.  Time 2 has the formula       :time   but the format is changed to Fixed Dec, 20, 3.

I ran the code under both JMP 16 and 17, with the same results.
