Invalid DateTime in Set Node

Describe the problem/error/question

I am getting the _createTime value from a Google Cloud Firestore node and I am trying to format it to something Nocodb can take. However, I keep getting the invalid DateTime error. This was working previously in an earlier N8N release. Is there someone that could let me know why I am getting the error? Thanks.

{{ DateTime.fromISO($json["_createTime"]).toFormat('yyyy-MM-dd hh:mm:ss') }}

What is the error message (if any)?

Invalidate DateTime

Please share your workflow

Share the output returned by the last node

"Invalid DateTime"

Information on your n8n setup

{{ new Date($json[“_createTime”]).toISOString().replace(‘T’, ’ ').slice(0, -5) }}
{{ DateTime.fromISO($json[“_createTime”]).toUTC().toFormat(‘yyyy-MM-dd HH:mm:ss’) }}

Thanks Fernanda.

{{ new Date($json["_createTime"]).toISOString().replace('T', ' ').slice(0, -5) }} 

works for me, but

{{ DateTime.fromISO($json["_createTime"]).toUTC().toFormat('yyyy-MM-dd HH:mm:ss') }}

does not.

It turns out the Timezone in the workflow Settings set to default seemed to have caused the error.


Once I’ve changed it to my local timezone, the original DateTime code works again.

{{ DateTime.fromISO($json["_createTime"]).toFormat('yyyy-MM-dd hh:mm:ss') }}


No more “Invalid DateTime”.



Amazing! I was having an issue today with the timezone too, mine was GMT -3 Sao Paulo, but it was setting it wrong so i had to search a solution to subtract 3 hours… :frowning:
