I believe what the sentence is supposed to say is "It usually presents at around 6:30 PM for the first time, the time a majority of families are cooking their dinners" I could be wrong, the sentence you put forwards is a little out of context.

How to make it correct? Here is what you need to do before you correct it: 1. learn the correct use of the verb "present" and decide it it is the correct word used correctly; 2. examine how many clauses there are and whether there is a verb in each clause. To enable helpers here to assess your work, you should also indicate: 3. what "it", the subject, is; 4. the context in which you are using "for the first time".

All three are incorrect! Sorry.

I agree with Ben that none of these are 'right', because they are all fairly meaningless. 'Present' is a transitive verb, needing a subject and an object. What is it? And whatever it may be, we need to know what it is presenting. 'It presents' makes no sense on its own. Are you talking about at TV programme? If so, you need to use a passive form of the appropriate verb, for example: 'It is shown' 'It is broadcast' You need to correct this first, and then think about fine-tuning the sentence. There's no point in fine-tuning a sentence that has no meaning.
