Is there a routine that can save a layer state by Date and Time?

unless I am missing something, could you explain how you would expect to create the layer state a bit more, ie. automatically at set intervals, upon the selection of a different pspace tab or other triggering event.  You could just incorporate the date and time in the name of the layer state.

Sure, I have created at macro that will toggle all the layers on and off with associated colors within the Tool Palette. I am trying to create a command that will backup the current layer state (Again by a time or whatever) then the layer change gets applied. I would like the layer state to be there; in case I need to roll back to the previous layers.

There are a number of built-in layerstate functions including: layerstate-save. These functions handle most of the work, so you do not need a lot of code.
Code - Auto/Visual Lisp: [Select]
  1. (defun c:LayStBu ()
  2.   (layerstate-save (strcat "Backup_" (rtos (getvar 'cdate) 2 8)) nil nil)
  3.   (princ)
  4. )
