As the moon slowly pulls away from the earth days and nights grow longer , and the earth's wobble will intensify . Will this have an effect on our time system ?

Yes, the time won't exist anymore.

There will be effects to be sure. Folk who use a lunar calendar will find that the year is longer since the moon will move through the night sky more slowly. It will also cause seasonal and tidal changes over time, too. So those of us who use a tidal calendar and a solar calendar will have some changes to make.
For part of what is implied in your question "[w]ill this have an effect on our time system?" the answer is no. We measure time based on the second --no matter what calendar we use-- and that is now based on an atomic event rather than astronomical events.

Yes, I believe it will. . .
While the meausrement of time has been refined through the ages (as someone pointed out, it is now measured by atomic clocks), it is still defined by observences of the heavens. (that is why every once in a while, you will hear of them making micro adjustment to the atomic clocks).
However, even if the measurement of time is based on the heavens, it is not very well thought out.
Take the month for example. The month is based on the orbit of the moon, but how many months agree with that? the answer is NONE (well, February in a leap year comes close).
Nope, our measurement of time was determined a long time ago (pun not intended) by the Sumerians who thought a 12 hour day (the day was measured from sunup to sundown), 60 minute hour and so on would be easy to use.
There was a movement back in the '60s or '70s for a decimal clock, with 100 seconds per minute, 100 minutes per hour and 20 hours per day (10 hours per half day), but it required re defining the length of the second and died a quick death. To many constants depend on the length of the second being what it has been for centuries.
I think we will have our time measurement as long as we have reason to meausre time.
Of course, this may not apply if we travel to other planets and stars.

time is realative. meaning each obsever expieriences time differently. because we here on planet earth live near eachother and are traveling at around the same speed we dont "notice" much difference. however, we judge time by the motions of objects in the sky such as the moon which gives us a month, the sun which gives us a year and the galaxies which gives us the age of the universe. so in the future, yes a day will be longer and a month will be longer as well. but unless we come up with a different understanding of time than the one einstein has given us, time relative to the speed of light will not change!!! hope this helps!!!!

you know.. before, it has been a debate whether the universe is static or not.. even Albert Einstein agreed that the universe is static.. but it has been shown that it isn't.. Hawkins, a physicist if i am not mistaken had studied about this phenomenon. it is then proven that after the big bang, the universe is expanding continuously/consistently then this means, as time passes the planets and stars move farther from each other .. then it can be concluded that many many many years from now if humans do survive, a day during that time would be 3 days or even a week of the present time..

What you suggest has no basis in fact, and I would argue it isn't happening. Time as a measurement of duration is fixed, currently based on cesium-133 atomic clocks.

just wait and see for yourself.
