is documented, and none is immediately obvious in the source code.

Or is the recommended way to convert a DateTime to a Unix timestamp and 
then use strftime?

Unfortunately, std.datetime does not currently support custom formatting
for any of the time point types (it's on my todo list, and I should have
finished years ago but haven't). In most cases, toISOExtString is what folks
should be using, but at this point, if you want a format other than those
provided, you're going to need to do it on your own somehow. There isn't
really a recommended way to do it. However, strftime would be one option,
and it takes a tm*, which has the time all split out like DateTime does,
so that would mean either setting all of its fields yourself, or converting
the DateTime to a SysTime and using its toTM() function to convert it a tm.
Converting it to a SysTime would probably be easier.
