Titanic Sinking Timer

[Ch1156]

i am making a timer that tells me how many seconds, minutes, hours, days and years ago the titanic sunk i am confused on where to start the calculation. It sank at 2:20 AM on April 10th 1912, i was thinking of doing liek a start and end time kind of like this old code i found, but how do i set the start time?

time_t endTime = time(0),
                           playTime = endTime - startTime,
                           hoursTime = playTime / 3600,
                           minutesTime = (playTime / 60) % 60,
                           secondsTime = playTime % 60;

#include <iostream>
#include <ctime>

using namespace std;

int main()
{
    time_t time_seconds;
    time_t time_minutes;
    time_t time_hours;
    time_t time_days;
    time_t time_years;

    time_t current = time(0);
    cout << "Current Time: " << ctime(&current);

    cout << '\n';

    cout << "The Titanic sank: " << time_seconds << " Seconds, "
         << time_minutes << " Minutes, " << time_hours << " Hours, "
         << time_days << " Days, " << " and " << time_years << " years ago" << endl;
}

One way, certainly not the only way...

Epoch time is based on the number of seconds since 1/1/1970.

First determine the number of seconds since 2:20 AM on April 10th 1912 to 1/1/1970.

Then, each time you run the program, add the number of seconds since 2:20 AM on April 10th 1912 to the current Epoch time to get the number of seconds since the Titanic sank.

*edit* My count from 2:20 AM on April 10th 1912 to 1/1/1970 is 30362320 minutes.
21071 normal days in years
14 leap years
less
2 hours 20 mins

I didn't try too hard to confirm that so you might want to check math.

So my guess is the Titanic sunk roughly Titanic Sunk = 3200825128 seconds ago and counting....
