Display Estimated Delivery?

I would like to display the new estimated delivery dates from the USPS along with the rates. Is this possible? Thanks.

The actual Date or the number of days?

I'm thinking the number of days. Since the USPS now quotes days based on the zip code I was curious is that data came back with the rates and if so could it be added in the module?

Did you try just setting the settings to ...

Check the box for: Display transit time

USPS Options
Select from the following the USPS options.
note: this adds a considerable delay in obtaining quotes.

Display weight
Display transit time

and set the method to NEW for:

USPS Domestic Transit Time Calculation Mode
Select from the following the USPS options.
note: NEW and OLD will add additional time to quotes. CUSTOM allows your custom shipping days.

CUSTOM
NEW
OLD

Most excellent. I must have missed this with all the new options to set. Thanks.

Where would be the most optimum way to alert the customer to the fact the although the USPS quotes delivery days, they do not guarantee said quoted delivery times?

There is a choice for CUSTOM, where you set your own number of days ...

Where would I enter custom dates? ... I just found it in the file. I've got it from here. Thanks for the help and direction.

For the CUSTOM settings, you would need to customize the USPS file itself:/
/includes/modules/shipping/usps.php

and make your changes to the section for:
function parseDomesticTransitTimeResults
