Any body knows the API name of the junction object Opportunity Product?

I can see this object in the the schema builder but it seems like I am not able to use this object trough the API.

Anyone?

Hi:

I have created a DateTime field in my custom object which is shown in the UI, is there any way to mask the time part and just show the date?

I need to have the field as DateTime because behind the scene it issues a SOQL and is compared against CreatedDate.

regards,
