Timestamps in MsBuild

I often need to include a timestamp in a build, either in naming a file or folder produced during the build, or using it in the content of a file.

MsBuild has built-in property functions that allow this to be fairly painless once you are familiar with the syntax.

The syntax for static properties is:
