What is a good definition of Time?

Jun 2018
Having checked there is not one really good definition of time yet in physics. Not a good definition for time in any dictionary I am aware of either. Here we are using a likely variable for years that we do not have even defined.

Toward the end, in the paper I wrote about time and time dilation (trying to get arXiv sponsor for at least a peer review), made an attempt to actual define time.

Everybody let me know what you think of my following definition.

Time is the past, present or future movement between particles or waves in any or all of three dimensions compared to the fixed speed of light thereby creating a forth dimension.

Dear webmaster even though you allow php programming on this posting page you do not have spell check why not? Should help allot on postings. A free javascript should be available?
