standard way to do wall clock timer / stopwatch in Unreal C++?

[Shmoopy1701]

Is there anything in Unreal to measure wall clock time elapsed at any two points in code?

Use case is a couple constructors taking way too long to run and want to log time elapsed from start to end of constructor.

So anything that depends on Tick() or delta time cannot be used.

Is the blueprint Now() node good enough for your need?

Get accurate real time should work. Thanks!

I use this:

double start = FPlatformTime::Seconds();
//slow code
double end = FPlatformTime::Seconds();
UE_LOG(LogTemp, Warning, TEXT("executed in %f seconds."), end - start);

Give fine accuracy in miliseconds range.
