* between time measurements.
 * <p>
 * This implementation is singleton-based and always uses UTC timezone. The clock
 * cannot be adjusted to different timezones to maintain consistent monotonic behavior.
 * Users needing local time representation should convert the result of {@link #instant()}
 * to their desired timezone:
 * <pre>{@code
 * Instant now = MonotonicClock.now();
 * ZonedDateTime local = now.atZone(ZoneId.systemDefault());
