Hi, if you take your sequence it is a kind of default.
Computer can go in front of time. Usually the time is the important information in written texts in this case.
If "computer" is after time, the computer is more important.
But: It also depends on context.
And context can supersede it.
Both computer and time are essential. The question is, what is the essential information you did not now yet.
Consider the dialogues:
Wann repariert der Techniker den Computer?
Der Techniker repariert den Computer nächste Woche.
better:
Der Techniker repariert ihn nächste Woche.
Was repariert der Techniker nächste Woche?
Der Techniker repariert nächste Woche den Computer.
(Note: in daily language you would answer:
Der Techniker repariert den Computer.)
