Create test data with createddate less than SystemToday in apex test class

Have you ever been come up with a case where you have to create test data with created date less than today. Is that possible??

In winter’13 salesforce introduced a static method on test class, loadData() method which can load the data from static resource. This method takes two parameters

1.Sobject token – to identify to which object the static data should be mapped.

2.Static resource name- From which salesforce load data, it can be a csv file with field names are file headers and respective cells having values.

Lets say I have a following piece of code which I need to cover from a test class.

public class TestLoad
{

public void TestAccounts()
{
    List<Account> a  = [select name from account where createdDate <:system.today()];
    if(a.size()>0)
    {
        for(Account ac: a)
        {
            //Process some logic
        }
    }
}
}

I can use the following code to cover the complete line of code.

@isTest
private class TestLoad_TC
{

    static testMethod Void TestLoad_TC()
    {
        Test.startTest();
        List<sObject> ls = Test.loadData(Account.sObjectType,'testAccounts');
        TestLoad insta1 = new TestLoad();
        insta1.TestLoad2();
        Test.stopTest();
    }
}

Here Test.loadData(Account.sObjectType,'testAccounts'), which loads the data from static resource.

The csv file headers should maintain the object field api name for the method to map the data from file to object.
