Universal Timer Macros

Making elapsed time based on gauge update cycle is simple to code and easy to understand.

A group of macros, but with an universal score could be :

<Macro Name="GetElapsed">
  (P:Absolute time,@2) (L:@1,@2) - abs
</Macro>
<Macro Name="SetElapsed">
  (P:Absolute time,@2) (>L:@1,@2)
</Macro>

And then using:

@SetElapsed(name_of_var,unit)
@GetElapsed(name_of_var,unit)

For example (pseudocode):

<Update>
   (A:TURB ENG ITT:1, celsius) 907 >
   if{  @SetElapsed(MyTimer,minutes)  }
   ...
   ...
   @GetElapsed(MyTimer,minutes) 5 >
   if{ do something }
   ...
</Update>

Both macros can be copied and pasted on every gauge so to have elapsed timers available for the entire code.
