Cannot create spring beans - spring

Question

I have spring application and have defined the Clock bean in my SpringMvcConfig.java as follows
#Bean
public Clock clock() {
return Clock.systemDefaultZone();
}
I am using it in my service
#Service
#RequiredArgsConstructor
#Slf4j
public class DeliveryEstimationService {
#NonNull
private final SalesChannelService salesChannelService;
#NonNull
private final MessageSource messageSource;
#NonNull
private final Clock clock;
public List<LocalDateTime> applyCutoffHoursToLocalDate(List<Integer> cutoffWindowHourList, int plusDays) {
return cutoffWindowHourList.stream().map(cutoffWindowHour -> LocalDateTime.of(
LocalDate.now(clock), LocalTime.of(cutoffWindowHour, 0)).plusDays(plusDays))
.collect(Collectors.toList());
}}
And I see this error
org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor$AutowiredFieldElement.inject(AutowiredAnnotationBeanPostProcessor.java:640)
... 83 more
Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'deliveryEstimationService' defined in file [/home/runner/work/checkout-service/checkout-service/target/classes/com/checkout/delivery/DeliveryEstimationService.class]: Unsatisfied dependency expressed through constructor parameter 2; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'java.time.Clock' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}
at org.springframework.beans.factory.support.ConstructorResolver.createArgumentArray(ConstructorResolver.java:798)
Can someone tell me why spring app cannot create the bean?
I had to use clock because I need to set fixed time for testing purpose
void getFixedClock(LocalDate date) {
fixedClock = Clock.fixed(date.atStartOfDay(ZoneId.systemDefault()).toInstant(), ZoneId.systemDefault());
doReturn(fixedClock.instant()).when(clock).instant();
doReturn(fixedClock.getZone()).when(clock).getZone();
}
