class内定义的静态量怎么识别为非静态量？

#include
using namespace std;
class Time
{
private:
int hour,minute,second;
static int baseHour,baseMinute,baseSecond;
static int timeToSecond(Time t)
{
int sum;
sum=t.hour*3600+t.minute*60+t.second;
return sum;
}
public:
Time(int a=0,int b=0,int c=0)
{
hour=a,minute=b,second=c;
}
static int timeBaseDifferent(Time t)
{
int i=timeToSecond(t);
int j=baseHour*3600+baseMinute*60+baseSecond;

};
int Time::baseHour=1,baseMinute=10,baseSecond=10;

倒数第三行少打了个大括号
