clock

问题 I'm still making my clock. I want to save/load my data from when I use the clock so when I close at a specific time(like January 23rd), when I re-open eclipse I can do something so it brings me back to said time. Any ideas? (Snippits requested) import java.util.Scanner; import static java.lang.System.out; public class Clock { public static void main(String args[]) throws InterruptedException { Scanner keyboard = new Scanner(System.in); out.print("Set the week and day."); String specday = null

问题 I am timing how long it takes to do three different types of searches, sequential, recursive binary, and iterative binary. I have those in place, and it does iterate through and finish the search. My problem is that when I time them all, I get 0 for all of them every time, even if I make an array of 100,000, and I have it search for something not in the array. If I set a break point in the search it obviously makes the time longer, and it gives me a reasonable time that I can work with. But

问题 Am I going mad? I'm running this on x86_64. #include <stdio.h> #include <time.h> #include <unistd.h> int main(int argc, char *argv[]) { printf("Clock: %f\n", clock() / (double)CLOCKS_PER_SEC); sleep(1); printf("Clock: %f\n", clock() / (double)CLOCKS_PER_SEC); sleep(1); printf("Clock: %f\n", clock() / (double)CLOCKS_PER_SEC); return 0; } This prints Clock: 0.002880 Clock: 0.002968 Clock: 0.003019 It clearly waits for a second at the sleep(1) lines, but the output is clearly wrong. If that

问题 I am currently working on creating a clock using python 2.7.5 and pygame. Here is my code so far: screen = display.set_mode((800,600)) running=True while running: for e in event.get(): if e.type == QUIT: running = False screen.fill((0,0,0)) draw.circle(screen,(255,255,255),(400,300),100,3) ang = 270 def clock(secs, mins, hours): ang = 270+6*secs dx = int(cos(radians(-ang))*100) dy = int(sin(radians(-ang))*100) draw.line(screen,(255,0,255),(400,300),(400+dx,300-dy),1) time.wait(1000) ang+=6

问题 I am creating data on several machines, processing the data in parallel, and then aggregating to a separate machine. What is the best way to sort the aggregated data by creation time, accurate to say, +/- 5 seconds? If all of the machines have their system time synchronized via NTP, is tacking on an integer timestamp, from the UNIX epoch, on each source machine, going to be reliable enough? 回答1: After puzzling over this for a very short time, the best technique I can think of so far would be

问题 I have a independent clock created in my application. The clock runs as a different thread in the activity, starting from a base time set by me. I update the clock using the difference between the uptimemillis when I set the clock, and the current uptimemillis. But the uptimetimer, can be reset by Android, and is ever reset when Android reboot. I only want to know if the uptime timer is reset, to know if the clock is still reliable. How? 回答1: According to the documentation you can use

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 2 years ago . I am trying to create a program which takes a target time (like 16:00 today) and counts down to it, printing each second like this: ... 5 4 3 2 1 Time reached How can I do this? 回答1: You can do this using python threading module also, something like this : from datetime import

问题 I am running QNX, I used a function to get clock cycles per second, uint64_t clockPerSec = getCPS(); uint64_t currentClockCycle = getCurrentCycle(); functions uint64_t getCPS() { return (~(uint64_t)0) /SYSPAGE_ENTRY(qtime) -> cycles_per_sec; } uint63_t getCurrentCycle() { return ClockCycles(); } then after running a function I do currentClockCycle = getCurrentCycle() - currentClockCycle; I am not using it through the whole applications, so I dont have overruns/overflow of the clock, just to

问题 I want to add/subtract given number of minutes to/from given given time and find out the resulting time. e.g. Suppose the given time is 11:30AM and number of minutes to add are 100 then the resulting time is 01:10PM How to do it in Haskell using the Data-Time library? I tried reading the docs on the Haskell site but couldn't get almost anything out of it. There is no example shown on that documentation site. Also the cookbook on the Haskell site doesn't contain any example for time

问题 I'm using weareoutman's clockpicker on my page. How to prevent click on input to show clockpicker or fade in overlay before clockpicker come to visible? I just wanted to fade in overlay before clockpicker shows. Click on "button" is working as desired. So far I have tried beforeShow function in clockpicker also e.preventDefault() and e.stopPropagation() -functions in jQuery. HTML: <div class="dialog"> <div>Clock:</div> <div class="input-group" id="clockpicker"> <input type="text" id="start
