I have two versions of the 10.8.5 Mountain Lion (12F45) InstallESD.dmg image. Unfortunately I don't have the exact download dates, as the installer timestamps were modified when copying the installer between filesystems.
Note that while the file checksums are different, the container checksums (hdiutil checksum -type SHA1 InstallESD.dmg) are the same for both images: 4F6191ACF280FCC5E45887212073F7B92E711D56. It seems there was only a change in the metadata or signature of the file.
