Unix Timestamp to Real Date & time

[#1]

I extract data from a database and part of this is a "start time" for a process. The main problem with this is that it is in UNIX format so therefore returns a 10 digit number, I know that the formula for converting this to actual date and time is as follows

( taken from Excel)

=CELL/(60*60*24)+"1/1/1970"

so changing a column in JMP should be straightforward but I can't seem to do it. The (60*60*24) is easy but what format do I have to set the +"1/1/1970" to to make this work?

I have attached a data table that contains some dates from the past 6ish years as an example. My feeling is that this might have been asked before but I can't see anything that relates to it.

Just an add to Jeff's post.  When I used his formula I got back the number of seconds.  I added the MDYHMS format to the formula to get date and time

Another add - talked with Jeff offline and he made a very good point.  Don't use the character string "MDYHMS" if you want to do some math with your time stamps.   Use Column Info to format your new times as continuous data.

Jeff/ Bill,

I noticed that it was in seconds as well but I used the formatting available to turn it into 'proper' time.

Thanks again.

Hi Bill,

I know this post is from forever ago, but I am trying to do the same thing and failing. I have the formula and all that input into the new column, but I cannot find the option to select m/d/y h:m:s for the date convention. I am only given the options to select the many variants of m/d/y. Is there something that I am missing to get the time included in the date output? Thanks.

You have clicked on "Date" for the selection of the format to choose from. Select "Time" and it will give you all of the Date/Time formats

Yup....knew I was missing something lol. Thanks!
