Column formula to round timestamp to nearest minute

[#1]

Hi,

Looking for a column formula to round timestamp to nearest minute. 

27/06/2017 12:21:13 PM  need to round to 27/06/2017 12:21:00 PM.

Any suggestions?

Cheers.

Hi @Onjai,

I'm sure there are other ways to approach this, but I've had luck with the following when I've needed to do that (this requires that you have a numeric :DateTime column):

Round(:DateTime / 60) * 60

(Edited: replaced with the simpler formula pointed out by Jerry)

Hope this helps!

Julian,

This worked just fine.

Thank you.

Hi Onjai,
If you're using version 14, you can right-click the heading of your Timestamp column, select New Formula Column->Transform->Round. You'll then get a dialog box to set the desired parameters (because you're wanting to round to the nearest minute, you'll just need to select "Nearest" from the dropdown and click OK). This is the resulting formula:
Round(:Timestamp / 60) * 60

I am using the latest version of JMP.  The transform worked as well.

Thank you!

:Time Stamp - Modulo( :Time Stamp, 60 );
