Wow. Thanks a ton guys. 

Second that - we Germans are pretty big in giving even big, big things very matter-of-fact names (just look up this).I would give it both a "technical identification" and a "name".
like EZU-3 “Enter Fancy Name Here”
(Experimentelles Zeitreise Unterseeboot)
(experimental time-travel(ing) submarine)
I'd add:My vote would go for Lord Tirians "Zeitboot" . It is accurate and, ahem, timeless, as a name.
But yes, Germans just love(d) to have abbreviations for more or less complex names. So stuff like SdKfz (Sonderkraftfahrzeug = Special Vehicle) or PaK (Panzerabwehrkanone = Anti Tank Cannon) are still all too common in the German military today (though the examples are from WW2).
Hah! When I lived in Berlin, I often only knew things by their acronyms. I shopped there every Saturday for 4 years, and never did find out what "KDW" stood for.But yes, Germans just love(d) to have abbreviations for more or less complex names.
