1. can you throw without a try/catch block - is this legal?

Of course, that's the point. Otherwise, there would hardly be a
difference between an exception and a simple goto statement.
2. if you can, why am I getting a warning at those throw statements.

How are we supposed to know? You didn't tell us what the warning says.

{ quoted banner removed. DON'T quote extraneous material. tia., -mod }

I did tell,

The warning says, - "Will never be executed "

Another example is a place like this...

if (ret==NULL)
   {
       throw new std::runtime_error("Could not start/reset timer"); <--
why?

   }

my guess is that the compiler has determined that ret could never be
NULL.

Also, don't throw a pointer.

    throw std::runtime_eror("could not start/reset timer");
