How to update date and time in header footer in PowerPoint 2010

Ok, so this may be stupid, but since Microsoft products are used heavily in my new work environment, I "have" to (well I don't have to, but I want to) learn shortcuts and things such as overlay modifiers, for example, what I am posting now, in how to update a date amongst slides.

So, I have been given a PowerPoint for internal weekly progress reports.  The PowerPoint had a master slide which I am familiar with since I did use PP for school presentations.  I tried to change the date on "the" master slide.  However, this did not update the date for all slides.  I tried to Google and look up a way to update a date/time insert.  All I found were how to simply insert the date or insert/change the date for headers/footers.  I was "unaware" that the date was inserted on the slides as a footer, and I was thinking I could insert a text box with some type of "code" for the date which would update automatically when changed.  At any rate, I was simply thinking about it too much and in a roundabout way.  I simply just needed to go to the Insert tab then Header and Footer.  There you can change the date and its format and then apply to all slides!  Stupid and small, but I have to become more efficient in other things other than just LaTeX.  I will be heavily involved with Microsoft products, such as Excel and PP.  Not that I was ever against using them, I'd just prefer other software.

This is a pretty neat little app.  If you don't have MathType and or don't want to use equation editor for Microsoft products (or similar), such as PowerPoint, then this is a nice way to display equations through an image.

Why:
I myself faced a lot of difficulties to read pdf in kindle (and mobile phones / internet tablets), specially the image based pdfs (scanned image pdfs). Got tired of zooming and scrolling while reading a nice book. So created this to help me 'dive into the reading'. I hope it helps you too.

Why free? Well, I like programming and I needed the tool, so I would have created it anyways :P
To run the app, just click those buttons on the left
Those will launch the app directly...
no hassle
It will use 'Java webstart' technology. You need to have latest Java in your computer.
The app does not modify the original pdf, it creates a new pdf with the new crop areas that you will draw.
If you run the offline version, it will create a shortcut on desktop (and also to programs menu on windows). You can use that to run the app without internet connection.
If you have internet connection, app will keep itself automatically updated, no need to worry about getting the latest version.
NOTE: The app does NOT upload any file / any data from user's computer, the pdfs are cropped on user's machine.
Another note: App may ask to connect to Google sites, don't worry, it does that only to check whether there is any updated version of the app. It's an open source app and I have no intent to collect any user data.
