Play on Words

Hi,

I would really appreciate some help on properly punctuating a "play on words". The phrase I need help with is "it is about time", more commonly stated as, "it's about time". Its colloquial use, which I am sure most are aware of, is to express something that has finally occurred after a waited delay. While that would be the expected, and first reading, of the phrase, I would like to punctuate it so it grammatically states that the implied "it" is about time. In other words, making time the subject of the phrase - I believe. Some modifications I have thought of, in no particular order are:

"It" is about time
"It", is about time
It, is, about time
It, is about time
It is, about time
It is, about, time

While this may seem vague, if properly punctuated, I am sure the intended recipient will understand.

Any help, or suggestions will be very appreciated.

Thanks
