I'm using the Airtable API to create a new base and a new table (called 'Raw Data') within it. All of my singleLineText fields are working fine, but when I add a final field named 'Last Modified' with a type of lastModifiedTime, I get this error back from the api call:

error: {
   type: 'UNSUPPORTED_FIELD_TYPE_FOR_CREATE',
   message: 'Invalid options for Raw Data.Last Modified: Creating lastModifiedTime fields is not supported at this time'
}

I haven't been able to find anything in the API docs or by googling about this. I would appreciate any help.

     Thanks,
