CTime Comparison Operators

BOOL operator ==( CTime time ) const;
BOOL operator !=( CTime time ) const;
BOOL operator <( CTime time ) const;
BOOL operator >( CTime time ) const;
BOOL operator <=( CTime time ) const;
BOOL operator >=( CTime time ) const;

说明:
这些操作符比较两个绝对时间,如果测试条件为真则返回非零值;否则返回0。

示例:
// CTime比较操作符示例:
CTime t1 = CTime::GetCurrentTime();
CTime t2 = t1 + CTimeSpan( 0, 1, 0, 0 ); // 1 hour later
ASSERT( t1 != t2 );
ASSERT( t1 < t2 );
ASSERT( t1 <= t2 );
