gettime

I am using a Zynq chip on a development board ( ZC702 ) , which has a dual cortex-A9 MPCore at 667MHz and comes with a Linux kernel 3.3 I wanted to compare the execution time of a program so first a used clock_gettime and then used the counters provided by the co-processor of ARM. The counter increment every one processor cycle. ( based on this question of stackoverflow and this ) I compile the program with -O0 flag ( since I don't want any reordering or optimization done) The time I measure with the performance counters is 583833498 ( cycles ) / 666.666687 MHz = 875750.221 (microseconds)

I'm writing a simple program, which checks if elapsed time is more than 1 seconds. I take start time with a clock_gettime(), then I call sleep(5), take new time and I check if the difference is bigger than 1; I sleep 5 seconds, then it should be greater than 5, but my program prints a strange result. this is the code: #include <stdio.h> #include <stdlib.h> #include <time.h> #include <unistd.h> int main() { struct timespec tv1,tv3,expected; struct timespec nano1; tv1.tv_nsec = 0; tv3.tv_nsec = 0; expected.tv_nsec = 400000; if(clock_gettime(CLOCK_MONOTONIC,&tv3) == -1){ perror(NULL); } sleep(5);

I used the following function, function datediff() { var dat1 = document.getElementById('date1').value; alert(dat1);//i get 2010-04-01 var dat2 = document.getElementById('date2').value; alert(dat2);// i get 2010-04-13 var oneDay = 24*60*60*1000; // hours*minutes*seconds*milliseconds var diffDays = Math.abs((dat1.getTime() - dat2.getTime())/(oneDay)); alert(diffDays); } i get the error dat1.getTime() is not a function.... That's because your dat1 and dat2 variables are just strings. You should parse them to get a Date object, for that format I always use the following function: // parse a date

is it possible to create a jQuery function so that it gets current date and time? I've been looking around documentation but haven't found anything so far... @nickf's correct. However, to be a little more precise: // if you try to print it, it will return something like: // Sat Mar 21 2009 20:13:07 GMT-0400 (Eastern Daylight Time) // This time comes from the user's machine. var myDate = new Date(); So if you want to display it as mm/dd/yyyy, you would do this: var displayDate = (myDate.getMonth()+1) + '/' + (myDate.getDate()) + '/' + myDate.getFullYear(); Check out the full reference of the

i've looking around how to do this and i found a lot of examples with complicated code. Im using this: var time1 = new Date(); var time1ms= time1.getTime(time1); //i get the time in ms then i do this in other part of the code var time2 = new Date(); var time2ms= time2.getTime(time2); and finnally: var difference= time2ms-time1ms; var lapse=new Date(difference); label.text(lapse.getHours()+':'+lapse.getMinutes()+':'+lapse.getSeconds()); This works great, except for one issue, the hours it gaves me are always +1 so i have to add to the code (time.getHours()-1) otherwise it gaves me one hour more
