/*tick : 用time()返回的秒數（從1970年到現在的秒數）mytime: GPS時間，距離當天0點的0.1ms數時間格式：  例如："%02d%02d%02d  %02d:%02d:%02d.%d"                其中整數內容從年、月、日、時、分、秒、毫秒排列             可以設置成"%02d%02d%02d  %02d:%02d:%02d" 這樣就沒有ms舉例如下：#include "CDate.h"#include <iostream>using namespace std;int main(){        CDate_T t( time(0) );        cout<<t.getDateTime()<<endl;        int hour ;        t.getDetail(0 , 0 , 0 ,  &hour ) ;        cout<<"hour is "<<hour<<endl;        cout<<"hour is "<<t.hour()<<endl;        CDate_T lastDay0 = CDate_T( t.getDayStart() - 3600*24 );        cout<<t.secTimeLen( lastDay0)           <<" sec from the begining of last day "<< endl; //現在距離昨天凌晨多少秒        t = CDate_T("020306 00:04:04.0");        cout<<t.getDateTime()<<endl;        t = t + 3600 ;        cout<<t.getDateTime()<<endl;        t = CDate_T( t.getTime() , 10*60*10000 ) ;  //從1：04調整到0:10        cout<<t.getDateTime()<<endl;}*/#ifndef CDATE_H#define CDATE_H#include  <time.h>#include  <string>#include <assert.h>using std::string;class CDate_T{	int tick;			// seconds geting from time() functions 	int mytime;			// number of 0.1ms from the begining of the days .public:	static int calmytime (int t);		// calc mytime , t is ticks    	static int calDayStart (int t);		// calc ticks of the the begining of day public:	CDate_T ();	CDate_T (const CDate_T & o);	CDate_T (int t);		//  t is ticks 	CDate_T (int t, int z_time);	// t is ticks , z_time is mytime	CDate_T (int year, int mon, int day, int z_time = 0);	CDate_T (const string & s, const string & format = "");	void setDateTimeFormat (const string & format);	int getDayStart() const ;	int getTime () const;		// get ticks	int getMyTime () const;		// get mytime	string getDate (const string & format = "%02d%02d%02d") const;	// output the string of date according format	/*   output the string of datetime according format */	string getDateTime (const string & format = "") const;	/*  get the detail the time infomation */	int getDetail (int *year = 0, int *mon = 0, int *day = 0, int *hour =				0, int *min = 0, int *sec = 0, int *ms = 0);	int year ();	int mon ();	int day ();	int hour ();	int minute ();	int second ();	int ms ();	int addSeconds (int t);		// add seconds . mytime will be change correspondly	int addMyTime (int t);		// add mytime  , ticks will be change correspondly	int secTimeLen (const CDate_T & t) const;	// seconds away from t . *this - t 	int msTimeLen (const CDate_T & t) const;	// ms away from t , *this - t 	CDate_T operator+ (int miao);	CDate_T operator- (int miao);	bool operator== (const CDate_T & o) const;	// comare between datetime .	bool operator!= (const CDate_T & o) const;	bool operator>= (const CDate_T & o) const;	bool operator<= (const CDate_T & o) const;	bool operator> (const CDate_T & o) const;	bool operator< (const CDate_T & o) const;private:	int comp (const CDate_T & t) const;	static string dateTimeFormat;};#endif
