Gnome-screenshot 3.1.2 uses filenames like this one

making it rather easy to see when it was taken.
The problem is that it uses the colon ( : ) character - making it impossible to access such an image from Windows.
Considering I take most of my screenshots so I can send them to Windows users this has caused some problems.
Is there any way to change the default name that is used by the screenshot tool to replace the ":" with "." or "," ?
