Hi - My initial research shows that n8n.io default timezone is New York Eastern time. However, our n8n.cloud server is running cron jobs and doesn’t seem to match the Eastern time zone for node executions.
The instance uses the Timezone you did choose when you created the instance. If you want to change it, you can change it in the settings of your n8n.cloud instance (log in on https://app.n8n.cloud and then click on the cog icon).
