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

Macros
A group of macros, but with an universal score could be the following. Both macros can be copied and pasted on every gauge so to have elapsed timers available for the entire code.
FS9 syntax:
<Macro Name="GetElapsed"> (P:Absolute time,@2) (L:@1,@2) - abs </Macro> <Macro Name="SetElapsed"> (P:Absolute time,@2) (>L:@1,@2) </Macro>
FSX syntax:
<Macro Name="GetElapsed"> <MacroValue>(P:Absolute time,@2) (L:@1,@2) - abs</MacroValue> </Macro> <Macro Name="SetElapsed"> <MacroValue>(P:Absolute time,@2) (>L:@1,@2)</MacroValue> </Macro>
Implementation
The above macros are called within update sections in the following way:
@SetElapsed(name_of_var,unit) @GetElapsed(name_of_var,unit)
Gauge Example (FSX)
This is an example gauge for triggering an engine failure after five minutes above a certain temperature treshhold. In order to capture the absolute start time for the event, a G:var "lock" has to be employed. In this example, the lock will "open" when the engine temperature falls below the temperature treshhold.
