IValueResolver won't work with AutoMapper

public class GetLinkByIdQueryMappingProfile: Profile
{
    public GetLinkByIdQueryMappingProfile()
    {
        CreateMap<GetLinkByIdQuery, GetLinkByIdRequest>();

        CreateMap<GetLinkByIdResponse, GetLinkByIdQueryResultDTO>()
            .ForMember(dest => dest.CreationDateAndTime, opt => opt.MapFrom(src => src.Link.CreationDateAndTime.ToDateTime()))
            .ForMember(dest => dest.ExpirationDateAndTime, opt => opt.MapFrom(src => src.Link.ExpirationDateAndTime.ToDateTime()))
            .ForMember(dest => dest.IsActive, opt => opt.MapFrom(src => src.Link.IsActive));
    }
}

public class GoogleTimestampToDateTimeValueResolver : IValueResolver<Timestamp, DateTime, DateTime>
{
    public DateTime Resolve(Timestamp source, DateTime destination, DateTime destMember, ResolutionContext context)
    {
        return source.ToDateTime();
    }
}

            .ForMember(dest => dest.CreationDateAndTime, opt => opt.MapFrom<GoogleTimestampToDateTimeValueResolver>())
            .ForMember(dest => dest.ExpirationDateAndTime, opt => opt.MapFrom<GoogleTimestampToDateTimeValueResolver>())
