[sr-dev] How to get dialog duration in miliseconds?

[Daniel-Constantin Mierla]

The problem is that buf is allocated on the stack, on a zone reserved 
for pv_get_timenows2() function, which is destroyed as soon as the 
function execution ends.

You either define buf as static, or you allocate it dynamically in the 
function and free it later.

Cheers,
Daniel
