drupal node_save created time

[fufu7755]

Hello, there are questions to ask you.
When I create a node using node_save, I want to change the created time. I use "created: 1322428031" to set the value of the created, but it does not work. How do I set it up?
Thank you.

@fufu7755 It's not possible from the client side, you'll have to do something on the back end (in a custom Drupal module) to make that happen. Probably hook_node_insert() is what you're looking for.

Thank you for your reply!
Another problem I have about field_images. A few days ago when I upload pictures, drupal gave me a warning:
Notice: Undefined offset: 0 in image_field_widget_form () (line 358 of /data/wwwroot/test.china-op.cn/modules/image/image.field.inc).
Notice: Undefined offset: 0 in file_field_widget_form () (line 533 of /data/wwwroot/test.china-op.cn/modules/file/file.field.inc).

Before I use field_images upload pictures has been normal, and I did not modify any code, field_images Number of values is Unlimited. My code format is:
        field_images: {
           und: [
             {
               'fid': 'xxxxxxxxxxxx'
             },
             {
               'fid': 'xxxxxxxxxxxx'
              }
           ]
         },

In addition, I set the value of field_images Number of values to 1, I can upload a picture.

Can help me analyze where the problem lies. Thank you.
