Translation:It is all simultaneous.
How would you say "it is everything simultaneously" (as in, gleichzeitig being used as an adverb)?
It's all simultaneous, or it's all at the same time. Sounds better, no?
Speaking of pronounce, the end of "gleichzeitig" sounds like "sch" . I mean, the sound of that last "g" sounds like "sch". Is that the actual pronounce?
