Alexa: Write Time(stamp) to Google Sheet

I have see the tutorial about the Time Zone in a Alexa skill, but that tutorial seems to be a bit outdated… Maybe somebody give me some (new) advice?

I want to do a simple skill:

  • Alexa asks for weight (like 88kg)

  • Alexa writes the weight into a Google sheet with the corresponsing time the weight was given. It does not even matter so much, what timezone the action has taken place…

  • I manage to write the weight input into a new line in the Google sheet.

  • But I have not managed to write the {timestamp} into the “date” variable. In the Google Sheet it says nothing or “0” or “{timestamp}”.
    What is the command that I am missing?

thanks for any help!
