Detailed Description

Interface for sampling a high-resolution representation of the current time. Primarily useful for statistics gathering of timing information for plugins that operate within the renderer. In a multicore environment time sampling is a little challenging and can incur overhead. To support multithreaded operation (i.e. for RslPlugin shadeops, procprims, rifs), the standard idiom is to measure the time differential across a single code execution block. The value should be stored in a per-thread (lockless) context then summed across threads when a total is required. Note, these totals can exceed "user time".
