Time values in subsequent rows

Hi guys!
I have a DAT table which contains values arriving with a frequnecy of 100 Hz.
I added second column with the time expressed in seconds. However the time is running in the same cell (first row, second column) while I would like to stamp it continously in the rows below.
I was thinking to use a Script DAT with the following comand: op(‘table3’).appendRow(op(‘select3’))
where table3 is the “output table” and select3 is the DAT in which I have the time running (coming from timer CHOP and then CHOP to).

Is the syntax wrong? Is there a more efficent way to obtain this result?
Thanks a lot!

Ideally you write the incoming value and the current time within the same python command. You did not specify how the values are coming in, but if it’s over network you can use the callback functions for OSC/TCP/UDP DAT to get the current time when a new value comes in, and then and write it together with the incoming value to two columns.
Does that help?
