According to the SVR4 Product Overview, SVR4 introduces new process-scheduler
architecture, and high-resolution timing services to support real-time 
processing.

The high resolution timers are based on the BSD system timing services, and 
give microsecond resolution.

If you want more information, you can try and get the SVR4 "System
Administrator's Guide" and the "Programmer's Guide:  System Services and
Application Packaging Tools."  I'm not sure if they are yet available though.
