How Do I Apply Different Active Time On A Rule, Applied Across Multiple Managed Entities

To attain this, the Active Time must be a variable, and this variable must be applied for each ME.  For instance, you have 2 ME's, and for this particular example we will call them ME1 and ME2.  Via GSE > Managed Entities folder, you will find ME1 and ME2

Managed Entities Folder

ME1

ME2

On each ME, there is an advanced tab which contain several fields, one of which is called "Var", a place holder for a certain value. For Name cell, key in the word best describes your variable, in this example we are going to call it "UNIVERSAL".  For options, choose "activeTime" from the drop down list.  For the Active Time cell, we will assign "AT1" for "ME1"; assign "AT2" for "ME2".  Click on the green arrow and set the scheduled time you wish for each Active Time

ME1's Active Time

ME2's Active Time

As for your RULE, go to the advance tab, where the "Active time" cell can be found, choose "var" and use the value we assigned earlier, which is "UNIVERSAL".  "UNIVERSAL" variable would point to AT1 for ME1; and on the other hand, "UNIVERSAL" variable would point to AT2 for ME2, thereby having different schedule for each ME

After saving the configuration, similar data view would be the result of which

ME1

Cell is highlighted in RED, meaning the RULE is within the Active Time window and that the RULE's critical condition was sufficed.

ME2

In the above screencap, the cell is highlighted in BLUE, indicating that the RULE is currently inactive (outside Active Time period)
