The Milky Way moves through space within the cluster of galaxies it is a member, and this cluster in turn moves through space towards yet another larger cluster of galaxies off in the direction of the constellation Virgo. The total speed is about 300 kilometers per second or so...
Our time is probably most related to the speed of our own galaxy, the current rotation of it around it's center, its black hole (being a million times the mass of our sun) & tightly grouped stars and remnants of other stars, and the other clusters being tugged around within it that add drag to the whole, and of those small clusters or gobbled galaxies that have their own rotation, but are still turning with the rest of the Milky Way group...
The Time we clock today, is to the rhythm of our current location in our galaxy...
the locations of the others suns and masses around us... it'll take some few million years times 10 for a complete rotation, so we'll keep this Time for awhile...
But Time could be faster or slower depending on your location... distance plays a factor as well...
Being closer to the galactic center may make Time faster, and being farther away the oppostie... and ebing WITHIN the galactic center may stop Time altogether and make it something else... your Space may switch with your Time, and vice versa, making your Time a whole new meaning and instance... while your space, or mass, becomes entwined with a whole new complex formation of Time... one that we've yet to discover, mainly since we can't get into a black hole to know for sure...
