Improve performance of call system.currentTimeMillis()

[Fangfengbin]

Hello



Some operators call system.currentTimeMillis() frequently and it is cost 
performance.

I want to use a thread to call System.currentTimeMillis and update a long 
variable millTime. All other module do not need call System.currentTimeMillis() 
and can get millTime directly.

I want to know your suggestion. Thank you very much.
