I'm writing a program and need to know how dates, versions, time, and numbers are formatted in the German Language
Example (in English)
Version 1.0.0 (Build 0)
How would that look in German?
Time and date
Time and date formats in technical publications and software can be made according to the ISO-8601. This norm is valid in German too (see here for many examples in German). See also this question for more.
There are many efforts to adapt the ISO 8601 to all texts written in German but still the older formats are widely used. These officially obsolete date formats were therefore reintroduced in the DIN 5008. Accoring to this a date can be written as follows:
Version numbering of software is done identical to their English counterparts. There is no need to change that in a German localization (this would even include your example "Build" - a term that is perfectly understood in the context of software).
Note that "version" translates 1:1 to the German "Version".
