Then I spent way too long on this fun code:

//finds Unix time (number of seconds since 1970)
//factors this number
//creates a string to be pasted into a LaTeX document
//sends this string to a file
//code proudly written by Rose DiFonzo, 2017, but you may steal if you would like

#include <iostream>
#include <time.h>
#include <cmath>

#include <fstream>

bool primep (long int N)
{
    for (int m=2; m<= floor(sqrt (N)); m++)
    {
        if (N%m ==0) return false;
    }
    return 1;
}


int main()
{
	using namespace std;
	
	int64_t divisorlist[1000];
    int64_t primedivisorlist[100][3];
	int counter (1);
	
	time_t timer;
	timer =time (NULL);
	cout<<ctime(&timer);
	
	//find alliquot divisors
	
	  for (int m=1; m<= floor(sqrt(timer));m++ )
    {

        if (timer%m == 0)
            {divisorlist[counter]=m;
        counter++;}
    }

	//identify repeats
	
    for(int m=counter-1;m> 0;m--)
    {

      int64_t quotient = timer/divisorlist[m];
     if (divisorlist[m] != quotient)
     {divisorlist[counter]=quotient;
        counter++;
    }}

    // now extract primes
	
    int bar=1;
    for(int m =2; m<=counter-1;m++)
    {
        if (primep(divisorlist[m]))
            {primedivisorlist[bar][1]=divisorlist[m];
            bar++;}
    }

    // now find powers of primes

    for (int m=1; m<=bar-1; m++)
    {
        int power=1;
        int64_t x = round(pow(primedivisorlist[m][1], power));

       while (timer % x ==0
              && x<=timer)

        {
           power++;
            x = round(pow(primedivisorlist[m][1], power));
       }
        primedivisorlist[m][2]=power-1;
   }
   
   ofstream outf("C:/Users/blah/blah/blahblah.txt");
   outf<<ctime(&timer)<<". Or $"<<timer<<" = ";
   for(int m =1; m<=bar-1;m++)
    {
        outf<<primedivisorlist[m][1];
        if (primedivisorlist[m][2]>1 )
			outf<< "^"<< primedivisorlist[m][2];
        if (m<bar-1) outf<<"*";
        
    }
	outf<<"$ seconds Unix time.";
   
   outf.close();
   
}

Actually, I approve of absolutely standard date forms. It is just too bad that the factored number of seconds since the start of the year 1970 is not it.
