/**
 * A Clock implementation that combines monotonic timing with wall-clock time.

 * This class provides precise time measurements using {@link System#nanoTime()}
 * while maintaining wall-clock time information in UTC. The wall-clock time
 * is computed from the monotonic duration since system start to ensure consistency
 * between time measurements.

 * This implementation is singleton-based and always uses UTC timezone. The clock
