"It is time now" or "It is now time"? [closed]

The position of certain time adjuncts in English is very flexible. Assuming your sentence is standing alone, now fits in every position: Now it is time. It now is time. It is now time. It is time now.

The default position of a time adjunct is at the end of the clause, so bringing it forward from that position gives it greater emphasis. Compare:

I played tennis yesterday.

Yesterday I played tennis.

Note that yesterday fits only in these two positions, whereas frequency adjuncts such as sometimes fit in three places:

Sometimes I play tennis.

I sometimes play tennis.

I play tennis sometimes.

As you see, the rules governing the position of adverbs in English are rather complex.
