Storing timestamp

Hello, I want to store time stamp after data get stored into csv file so, How do I create timestamp and store it along with data in csv file?

I think a change node can generate a timestamp.

If not, a function node with var ts = Date.now(); will do the job.

If you want more help, provide more details & a demo flow.

If the target output is a CSV file, you also need to think about the output format. If you follow Steve's advice, you will most likely end up with ISO8601 format, e.g. 2021-05-31T15:45:00.000Z. Meaning that the timestamp will also be in the UTC timezone. That's a common format clearly readable by humans and machines but not all applications will recognise it.
