we have time zones here on earth, is time measured differently in deep space?

Answer 1

Time is not constant. Time is relative to the observer's frame of reference. The observer's frame of reference is relative to the observer's location relative to sources of gravity and observer's motion in their frame of reference. Basically, it's all relative.

Highly accurate cesium based "atomic" clocks in supersonic jets have shown differences in what the "time" is when they're returned to the location where the "master" clock was left in the lab on the ground. This was caused by the clocks on the jets having had different relative motions than the one left behind.
If two atomic clocks were synchronized and one was put on top of Mt Everest and the other left at the base, after a week they would show two different times--one clock being farther away from the center of the earth or source of its gravity well.

Answer 2

Not really. One second is one second for the most part. There are some exceptions, but they are rare. Time is less dependant on where you are as to how fast you are moving. But with respect to our present probes and spacecraft, time is measured in the same way but usually based on GMT time.

Answer 3

In deep space time is measured by the isotope clock in chyene mountain.

Answer 4

Yes but it is still in reference to time on earth because time does not exist any where else.

Answer 5

Time is relevant, time is real, time does exist and time waits for no man.

In space flight, mission time - length of hours and minutes since lift off (now we know where t minus comes from, t plus is mission time) or for reference Universal Coordinated time.

Answer 6

yes
