Need to compare two different time formats

Describe the problem/error/question

Hello everyone,
I would like to compare datasets with two different time formats. Not a problem at all, but in my case it is. From one system I’m getting ISO Date/Time. From another system I’m getting the ISO Date and Time in two different fields.

For example.
System 1 gives me:
dateModified: 2024-02-16T14:00:04+00:00
System 2 gives me:
Last Date Modified: 2024-02-16T00:00:00.000Z
Last Time Modified: 1754-01-01T12:52:28.063Z

I dont know why System 2 uses such a stupid database design (at least in my oppinion) but thats not what it is about here. I need to combine the 2 fields from System 2 to one date/time field, so I can compare it with the date/time from System 1.

Any ideas?

Please share your workflow

Share the output returned by the last node

ERROR: Invalid date format
Should get: 2024-02-16T12:52:28.063Z

Information on your n8n setup

  • n8n version: 1.27.3
  • Database (default: SQLite): SQLite
  • n8n EXECUTIONS_PROCESS setting (default: own, main): Default
  • Running n8n via (Docker, npm, n8n cloud, desktop app): Docker

hello @lordimac

you can get the proper datetime from the system 2 with Edit Fields node and this payload:

Thank you very much!


The time node is much easier to format with

Hello, no it does not work with the two inputs. I guess the time value needs to be converted.

The value “1754-01-01T12:52:28.063Z” is not supported!

Convert the data to a common format eg as in my example. From this you can then use the format from your desired format easily

That one doesn’t solve the original issue.
