Before you talk about "local time" you must first understand
"time."  What is "time"?  Or maybe, the question is: WHY is
time?  Does space have time, or do just masses have time?  Is
there more than one dimension of time?  It appears to be a
quantum thing/process; we use it, and are ruled by it, but we
just don't know very much about it.
