time

问题 I've the following problem, that showed up when I installed my webapp's war on a virtual linux server. Here it is: my server system time seems correct, in fact typing date on shell comes out with: Mon Apr 11 11:47:30 CEST 2011 which is my "wall clock time". Even mysql works fine, if I do select now(), I get: mysql> select now() -> ; +---------------------+ | now() | +---------------------+ | 2011-04-11 11:52:57 | +---------------------+ 1 row in set (0.01 sec) But my application (Spring

问题 I have a little Bash script which suspends the computer after a given number of minutes. However, I'd like to extend it to tell me what the time will be when it will be suspended, so I can get a rough idea of how long time I have left so to speak. #!/bin/sh let SECS=$1*60 echo "Sleeping for" $1 "minutes, which is" $SECS "seconds." sleep $SECS && pm-suspend The only argument to the script will be how many minutes from now the computer should be suspended. All I want to add to this script is

问题 I have a small android problem, I have a requirement to have a timer to calculate the duration from the time a specific activity was open till a certain button in that activity is clicked, simply how long the activity was open. While googling around I found TimerTask but this seems to run a thread for a certain interval only though and doesent seem ideal for the job from my little Android experience Any idea on how to calculate the duration? Preferably in a very simple manner Any help is very

问题 I'm too lazy to fill out my time sheet at work by the end at the end of every month, so I've started adding some functions to our PDF form. Acrobat Pro offers to make advanced calculations using JavaScript, but I'm stuck with this problem. I have two fields in which I enter the time when I start/end working. I want to calculate my overtime and output the result in a third field. however, I want the output to be decimal, so when I make half an hour overtime, the result would be 0.5 Example: my

问题 I'm looking for a way to save the time in a HH::MM::SS fashion in C++. I saw here that they are many solutions and after a little research I opted for time and localtime . However, it seems like the localtime function is a little tricky, since it says: All calls to localtime and gmtime use the same static structure, so each call overwrites the results of the previous call. The problem that this causes is shown in the next snippet of code: #include <ctime> #include <iostream> using namespace

问题 I want to run a piece of code at exact time intervals (of the order of 15 seconds) Initially I used time.sleep(), but then the problem is the code takes a second or so to run, so it will get out of sync. I wrote this, which I feel is untidy because I don't like using while loops. Is there a better way? import datetime as dt import numpy as np iterations = 100 tstep = dt.timedelta(seconds=5) for i in np.arange(iterations): startTime = dt.datetime.now() myfunction(doesloadsofcoolthings) while

问题 I was wondering how to make a time range for AVAssetExportSession from time stamps such as: NSTimeInterval start = [[NSDate date] timeIntervalSince1970]; NSTimeInterval end = [[NSDate date] timeIntervalSince1970]; The code that I am using for my export session is as follows: AVAssetExportSession *exportSession = [[AVAssetExportSession alloc] initWithAsset:asset presetName:AVAssetExportPresetHighestQuality]; exportSession.outputURL = videoURL; exportSession.outputFileType =

问题 I need to display the time but it must start from 00:00:00? I've got the following but it uses the current time. print(date("H:i:s")); 回答1: As an alternative to mktime() , try the newer DateTime class, eg $dt = new DateTime; $dt->setTime(0, 0); echo $dt->format('H:i:s'); // Add one hour $dt->add(new DateInterval('PT1H')); echo $dt->format('H:i:s'); Update The flexibility of DateInterval makes this a very good candidate for a timer, eg // add 2 years, 1 day and 9 seconds $dt->add(new
