Sulayi DateDiff function brod.

DateDiff( interval, date1, date2)

Sa imo case;
DateDiff("h", Login, Logout)

Icheck lang kung pareha ra syntax sa java, vbscript man gud ako gamit karon.

TS ingon ako migo.. daghan ra man sa google mga example about dateUtils mo computer sa difference duha..
ingon pud sya no need na e save ang difference instead pwede ang time in or timeout ra..

nangita pa ko bro.. medyo busy man gud.. nangita ko sa Date og Calendar nga mga functions.. wa pa ko naka tiwas og testing..

tagaan nya tika kung maka kita na ko..

import java.util.Calendar;


public class Main {


  public static void main(String[] args) {

    //Get Instances of Calendar to get System Date
    Calendar timeIn = Calendar.getInstance();
    Calendar timeOut = Calendar.getInstance();
    
    //Variables for HOUR IN (for manual input of time in)
    int hourIn = 8, minIn = 30, secIn = 15;

    //Variables for HOUR OUT (for manual input of time out)
    int hourOut = 17, minOut = 5, secOut = 35;
    
    //Setting time in
    timeIn.set(timeIn.get(Calendar.YEAR), timeIn.get(Calendar.MONTH), timeIn.get(Calendar.DATE), hourIn, minIn, secIn);

    //Setting time out
    timeOut.set(timeOut.get(Calendar.YEAR), timeOut.get(Calendar.MONTH), timeOut.get(Calendar.DATE), hourOut, minOut, secOut);
    
    //Show the Time IN and TIME OUT
    System.out.println("Time In: "+timeIn.getTime());
    System.out.println("Time Out: "+timeOut.getTime());
    
    //Experiment as seen in this link -> java - Compare hours and minutes - Stack Overflow
    long hours = timeOut.getTimeInMillis()-timeIn.getTimeInMillis();
    hours = hours/(1000 * 60 * 60);

    System.out.println(hours+" hours of work");

  }
}

Output is still in HOURS.. wala pa ko down to SECONDS nga computation, ako pa gisuwayan..
