In this cpp date example we will learn how to display current date and time.
For this example we import two packages
#include<cmath> |
Examples
#include<iostream>
#include<cmath>
#include <ctime>
using namespace std;
int main()
{
time_t t = time(NULL);
tm* timePtr = localtime(&t);
cout << "seconds= " << (timePtr->tm_sec) << endl;
cout << "minutes = " << (timePtr->tm_min) << endl;
cout << "hours = " << (timePtr->tm_hour) << endl;
cout << "day of month = " << (timePtr->tm_mday) << endl;
cout << "month of year = " << (timePtr->tm_mon)+1 << endl;
cout << "year = " << (timePtr->tm_year)+1900 << endl;
cout << "weekday = " << (timePtr->tm_wday )<< endl;
cout << "day of year = " << (timePtr->tm_yday )<< endl;
cout << "daylight savings = " <<(timePtr->tm_isdst )<< endl;
cout << endl;
cout << endl;
cout << "Date " <<(timePtr->tm_mday)<<"/"<< (timePtr->tm_mon)+1 <<"/"<< (timePtr->tm_year)+1900<< endl;
cout << "Time " << (timePtr->tm_hour)<<":"<< (timePtr->tm_min)<<":"<< (timePtr->tm_sec) << endl;
return 0;
}

This will return below out for the current date
seconds= 36
minutes = 45
hours = 7
day of month = 22
month of year = 1
year = 2021
weekday = 5
day of year = 21
daylight savings = 0
Date 22/1/2021
Time 7:45:36

Time manipulation |
|
difftime
|
computes the difference between times (function) |
time
|
returns the current time of the system as time since epoch (function) |
clock
|
returns raw processor clock time since the program is started (function) |
timespec_get
(C++17)
|
returns the calendar time based on a given time base (function) |
Format conversions |
|
asctime
|
converts a tm object to a textual representation(function) |
ctime
|
converts a time_t object to a textual representation(function) |
strftime
|
converts a tm object to custom textual representation(function) |
wcsftime
|
converts a tm object to custom wide string textual representation(function) |
gmtime
|
converts time since epoch to calendar time expressed as Universal Coordinated Time (function) |
localtime
|
converts time since epoch to calendar time expressed as local time (function) |
mktime
|
converts calendar time to time since epoch |
