Yes it will, in fact our whole gps satalites take those microseconds into consideration, because it wouldnt work correct otherwise.
Blondu, the main thing here isnt space, its gravity, since there isnt a big difference of gravity between here on earth and a bit above us the difference of time is very small, but it is. In fact i think someone even done the experiment, and saw that the clock in space was ticking faster.
To simply say it - the more stronger gravity is the more slower time will pass.

So what time is then?
Gravitation field distorts space-time fabric which affects "time" this is called time dilation and is a know fact not something i have just came up with. So the more gravity the slower "time" will pass.
And yes, the faster you go the slower the time. And it is true that for the one who goes slower "time" goes faster.

Actually, I think yes. Gravity has a small effect on time in general relativity. The GPS system actually has to account for this, or it'd be off by quite a bit.
It's the mathematics that underpin this, maths which makes time look very much like space, that makes physicists have funny notions about what it is. I think the Scott Adams post is a little off - he doesn't really grasp what's being claimed and takes it too far - but he's usually able to stimulate interesting conversations.
This is slightly different. It's about the speed you travel at. If the twin is in a ship travelling near the speed of light, time passes slower for him.

Everything moves, works, is done and etc faster there, so the clock is working the same, just that in that zone "time" passes faster.
In our universe there are billions of places where time passes faster or slower compared to us here on earth.
So if you are there you wont even feel the difference, because to you it will look normal. For eg. theorically you got into black holes gravitaion field and it was starting to suck you in. You wouldnt feel a difference, so had watch on you and it showed that you got sucked in an hour or month or more. To those who are outside of black holes gravity field it will be much more then your watch showed. Even though you and they who are outside wouldnt feel anything different, they would feel that time is passing at its normal speed.
Hope i was at least a bit clear, since its hard to explain in english

Depends on the clock. The kinds of clocks they use in situations where you need to be extremely accurate (like GPS) are based on atomic decay - radioactive elements (even mildly radioactive ones) decay in a random way, but on average, a lump of it decays at a constant rate. The clocks measure how much radiation is coming out.
Your digital watch uses a crystal which is made to resonate electrically - it wobbles at a particular frequency, like a tuning fork.
With an older wristwatch, a coiled spring pushed a load of gearing really slowly. Centuries of research made the mechanisms reasonably accurate.
A grandfather clock has a pendulum which rocks at a steady rate. This is geared down to drive the clock hands.
Does this answer your question?
Pretty much. Didn't see your post before replying! I'll cite the "great minds think alike" post.

Normally we're supposed to agree upon a definition of time before we can discuss its existence, but it always comes down to a dimension in which we can measure the "sequential distance" between two events. This fundamental quantity is called a time inverval. And it's so trivial we use it every day. Even you used the word time about 3 times on this page alone. And putting it between quotation marks doesn't make it any less real. Saying time doesn't exist would be as absurd as saying "space doesn't exist, hence length doesn't exist".
Yes I know that, but the Twin Paradox sally mentioned only concerns the effect of time dilatation caused by relative velocity.
A clock basically creates a scale in the dimension of time, like you would put a distance scale on a map. So if time would go "slower" or "faster", the scale of the clock has changed without us realizing it. I think this is what you were trying to ask for.

Doe maar even in het nederlands. Het probleem is dat ik niet weet wat ervoor zorgt dat een klok tikt en waarom ze net zo lang tikt. Uiteindelijk hebben wij die tijd vastgezet. Wij hebben bepaald wat een seconde is. Dus je zou verwachten dat die klok, waarvan het ritme door ons is vastgezet, altijd en overal even snel tikt.
Maar dat is dus niet zo?

Yes it does, but i didnt mentioned Twin paradox, i tried to explain using gravity, and i think i was right, and the someone else said about twins.
Tijd en afstand zijn continue grootheden, dus is het nodig om een soort van schaaleenheid te creëren vooraleer we tijdsinvervallen kunnen gaan vergelijken. Dit in tegenstelling tot discrete grootheden; bijvoorbeeld als we appels tellen is het evident dat er een elementaire eenheid bestaat, die hier overeenkomt met een gewoon natuurlijk getal.
Absolute tijd bestaat niet. En als tijd 'samengetrokken' of 'uitgerokken' wordt, merken wij daar niks van omdat onze persoonlijke tijdsschaal meeverandert. De beste analogie is gewoon als ge u inbeeldt hoe het zou zijn als wij ineens zouden ineenkrimpen, en dat onze zakmeter is meegekrompen. Vervolgens zet ge een paar passen tot als ge volgens uwe meter 2 meter verder zijt. Voor uzelf zijt ge idd 2 meter voortbewogen, maar voor iemand die niet gekrompen is zijt ge pakweg maar enkele centimeters vooruitgegaan.
