%description:
Test opp_get_monotonic_clock_usecs() implementation. Sleep for some time, 
and measure how much time has elapsed according to opp_get_monotonic_clock_usecs().
The two must match reasonably.

%activity:
int sleepUsecs = 750000;  // 0.75s
int marginUsecs =  10000;  // 0.01s

int64_t startTime = opp_get_monotonic_clock_usecs();
usleep(sleepUsecs);
int64_t endTime = opp_get_monotonic_clock_usecs();
int64_t elapsedUsecs = endTime - startTime;

EV << "sleep(" << sleepUsecs << "us), elapsed: " << elapsedUsecs << "us\n";
EV << ((elapsedUsecs >= sleepUsecs && elapsedUsecs <= sleepUsecs+marginUsecs) ? "OK" : "WRONG") << "\n";
EV << ".\n";
