Improved Timing Services
•Special Timer class implements same services as java.util.Timer with improved semantics:
–Not affected by changes in system clock
–Uses system “up time”, measured in nanoseconds
•PercThread shadows java.lang.Thread; implements sleepUntil(), waitUntil(), and cpuTime()
•PERC VM allows configuration of tick period and time slice duration
