Time-relation clauses use expressions such as 的时候, 以前, 以后, 之后, 之前 and often place the time frame before the main event.

wǒ dào jiā de shíhou, tiān yǐjīng hēi le = when I arrived home, sky already dark LE
在目标语言中
Temporal links use قبل أن, بعد أن, عندما, بينما and related structures.

Learners may confuse before/after clauses and nominal temporal phrases.
Same block, different coding
Both languages use this block strongly, but they signal it differently. Focus on form changes, not only meaning.
