Error parsing time with format "Y-m-d H:i:s" in generated go client

Description

I'm using swagger-codegen to generate go docs from Laravel project.

When using the generated go client, I keep getting error parsing time "2022-10-11 10:29:16" as "2006-01-02T15:04:05Z07:00" when trying to fill the model after calling an API

In the initial project, the annotation set for this field is
* @OA\Property(property="purchase_date",type="string", format="date-time")

In the generated go client by swagger, the field is
PurchaseDate time.Time json:"purchase_date,omitempty"``

Swagger-codegen version

3.0.34

Swagger declaration file content or url

snippet from yaml file

PurchaseResource:
      title: purchase_resource
      properties:
        id:
          type: integer
        external_id:
          type: string
        purchase_date:
          type: string
          format: date-time

Command line used for generation

swagger-codegen generate -i api-docs.json -l go --api-package SubscriptionsClient -o ./client-go

Start with the generated Go model's PurchaseDate field and the swagger-codegen generate command, then trace how the YAML date-time schema becomes time.Time. Reproduce the failure using the shown timestamp; done means the generated client handles the documented value consistently or the required input format is clearly documented.
