I know, the first thing you're going to say is "Why would you be doing that?".

I have an app that extracts data daily from multiple databases and writes to an excel file. We noticed, after running it every day since Jan '04 that some of the data isn't right.

I want to add to my app so after extracting the data and writing to the excel file, it will change the system date to the next day until now.

So I'll start the app with my system date as Jan/01/04 and it will go through each day for me, just trying to avoid sitting here changing my system date after each time the app has run (manually).

Thanks.
