- Make your selection
- Edit -> Copy Merged
- File -> New (Photoshop should automatically suggest a new canvas size to match the selection size)
- Edit -> Paste
- File -> Save As (PNG)
- Rinse and repeat... (keyboard shortcuts are handy here)

There are 2 ways to change the modification/creation meta data. From the file-system's perspective and within the file's metadata.
1. Changing file-system modify/create date/time
Windows
Depending on your OS, windows you can use a tool such as File Cosmetic or Finders Keepers. See this page for more of them.
File Cosmetic
Finders Keepers
MacOSX
You can use the touch command (man page), similar to other unixes.
For example:
% touch afile
% ls -l afile
-rw-rw-r-- 1 saml saml 0 Jan 23 22:31 afile
% touch -m -t 198001010000 afile
% ls -l afile
-rw-rw-r-- 1 saml saml 0 Jan 1 1980 afile
2. Changing the modify/create date/time within file's metadata
Commandline
You can use the commandline tool, exiftool, to manipulate metadata within various file types such as TIFF & PSD.
DateTimeOriginal before
% exiftool '-DateTimeOriginal' -f j.psd
Date/Time Original : 2009:05:31 08:32:08
Change the date time
% exiftool -overwrite_original "-DateTimeOriginal=1981:07:01 00:00:00" j.psd
1 image files updated
DateTimeOriginal after
% exiftool '-DateTimeOriginal' -f j.psd
Date/Time Original : 1981:07:01 00:00:00
NOTE: Further exiftool resources such as the main site & forum.
GUI
You can use the GUI on Windows, ExifToolGUI, to make the same types of changes.

The PNG format can not hold the minimum information that is contained in an image in Photoshop, even if it's a single layer RGB image. For example, the PNG format doesn't support color profiles, and an image in Photoshop always has a color profile.
So, saving as PNG is really exporting. When you load the image into Photoshop again, there is no guarantee that all settings are the same.
