present perfect vs past perfect [closed]
What's the difference between the following examples:
I noticed that the clock had stopped.
I noticed that the clock has stopped.
Some of them say that if the emphasis is laid on the subordinate clause then present perfect tense can be used, while some say if the emphasis is laid on 'noticing' then past perfect tense is to be used. How correct is this explanation?
Solution 1:
You can always use (1). You should not use (2) if the clock is no longer stopped.
