I would change the first line below and add one line and one 
parameter(dateTimeColumn). This assumes that the date/time is converted into 
seconds or milliseconds).

add 1 to uNames[item pColumn of l]["Count"]
if item dateTimeColumn of l > uNames[item pColumn of l]["DateTime"] then put 
item dateTimeColumn of l into uNames[item pColumn of l]["DateTime"]

Then the returned array will still have the keys of all unique drivers and each 
key will have 2 keys "Count" and "Datetime"

All of that works perfectly.  Thank you everybody!

Let's through a layer of complexity in here... each of of those names has 
another column with a time associated with it, for instance "13:02:58"
 I would like to only show the LATEST time associated with that particular name.

Premise behind this whole exercise:  I have a list of drivers and I want to 
produce a report that shows the driver name, number of jobs (both of these 
accomplished through the last script) and when they finished their last 
delivery.

Should I just break this out into a separate function or would it make sense to 
modify this function to fit these additional needs?
