How to create a field with postgres schema definition

[Nik]

According to the docs it should be possible to define a pg schema: Fields | Directus Docs

However when i try to create a timestamp without time zone it is nevertheless created as timestamp with time zone

My schema definition looks like this:

{
   field: 'time_of_call',
   type: 'timestamp',
   schema: {
      default_value: null,
      is_nullable: true,
      schema: 'timestamp without time zone'
    },
    meta: {
       interface: 'datetime',
       display: 'datetime',
       display_options: {
           format: '24h'
        },
        note: 'Original datetime value from source'
     }
}

Am I doing that wrong?
Or is rather my vibe partner right, concluding, that Directus is simply ignoring the pg schema.

Thx in advance for digging into this.

Turns out that dateTime defaults to timestamp without time zone while timestamp defaults to timestamp with time zone on postgres.

This definition is working now for me:

{
	field: 'time_of_call',
	type: 'dateTime',
	schema: {
		default_value: null,
		is_nullable: true
	},
	meta: {
		interface: 'datetime',
		display: 'datetime',
		display_options: {
			format: '24h',
		},
		note: 'Original datetime value from source',
	}
}

Doesn’t answer the initial question, tho, how to define a specific postgres field type.
