The example was written long before we put any import statements in examples, and because it involves std.datetime, and it's in druntime, it can't be a ddoc-ed unittest, which is why the circleci stuff has never complained about it.

I just realized that the publictests checking is only done for Phobos:

Well, it wouldn't have helped in this case. It also doesn't affect druntime all that much, since most of druntime's public modules don't depend on each other much. But it doesn't hurt to add a check.
