If you want to eg talk about the past or future, you can put the markers for the different times into your verbs (like English or German do with grammatical tenses) or you can put those markers into other parts of the sentence (like English or German also do).
Eg in colloquial English you can say 'tomorrow I go to the market' and be well understood. Even if in print you would put it as 'tomorrow, I will go to the market'.
