clock

I was trying to create a timer that depends on the system clock. That means when the system time changes it should affect the expiry of this timer too. So I thought, creating a timer based on CLOCK_REALTIME should do the trick. But when this timer is armed to expire after 60 sec and when I advanced the system clock by 32 sec (using date command), the timer expired exactly after 60 sec. It didn't expire 32 sec earlier. So I calculated the time elapsed for CLOCK_REALTIME and CLOCK_MONOTONIC clocks between the 2 timer expiry. It showed 92 secs for CLOCK_REALTIME and 60 sec for CLOCK_MONOTONIC,

My Nexus S comes with a default clock application where I can set an alarm. When I set an alarm then I see a little clock in my status bar. If I go to 'Manage Applications' or 'Running Services', I would expect to see Clock there, but I don't? If I go to 'All' from 'Manage Applications', then I do see the Clock app, and I can Force Quit it, however the clock in the status bar still appears. If the default Clock application never appears in Running Applications or Services because it is part of the system, then can developers access this Clock app? For instance I am creating an alarm

This question already has an answer here: Is there any way to get the tamper-proof date and time on iPhone? 1 answer So, I'm developing an app that is based on the time, but with NSDate an user can easily hack the application by changing system time of the device. So I might want to use a better method for retrieving time. How can I do this? Is there an easy way to retrieve time from internet? Ben-G Checkout this Google Library: https://github.com/jbenet/ios-ntp After the library is set up you can use it with the following line: [NSDate networkDate]; A similar question has also been answered

Is their a way to execute a delegate or event in C# when the seconds, minutes, hours,... change in the system-clock, without using a timer that checks every millisecond if the property has changed and executes the event with a delay of maximum a millisecond. I thus want to avoid polling and fire an event at a certain time. dtb If your question is: "How do I execute a delegate every full second/minute/hour?" For minute and hour intervals, you could do something like shown in my answer in this SO question: How to generate event on a specific time of clock in C#? This should be fairly accurate,

How can I retrieve wall-time in Python using the standard library? This question, and this question would suggest that something like clock_gettime(CLOCK_MONOTONIC_RAW) or /proc/uptime are most appropriate on Linux. On Windows, time.clock() has the desired effect. I would use time.time() , but the function is not guaranteed to return monotonically (and linearly) increasing time values. Victor Stinner wrote a Python implementation of a monotonic timer . See http://bugs.python.org/issue10278 for the discussion and the docs for the upcoming 3.3 release referencing the new feature (coded in C).

We have a couple of ec2 instances on amazon, and we used amazon AIM Linux to set up. The instance type is m1.medium. Everything is going well until this week. We found from log file that there would be a huge clock drift happened suddenly, and sometimes there has a 5-minutes discrepancy。 I would like to ask if anyone else encounter this problem? How to deal with it? Time drift can occur due to over utilization of your instances resources. I would encourage you to check you cloudwatch CPU graphs to try identify if your CPU was being over utilized. If you are running amazon linux AMI, NTP is

I wanted to make a simple program where the user has to enter a prompted number(1-4). Where the conditions of continuing is based on entering the number in the amount of time as defined by which level the user has selected and, of course, entering the correct number. The problem is that the program recognizes if the number is correct, however you can take as long as you like and it won't stop the game. This "15

I have been trying to create a program that will output a working digital clock that will allow me to quickly access the date and time. I have the code to parse the time, however, I'm having difficulty updating the textview. I have this: `public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); timer = (TextView)findViewById(R.id.timer); time = new Time(); time.setToNow(); timeString = time.toString(); changeTime = Parser(timeString); time.setToNow(); timeString = time.toString(); changeTime = Parser(timeString); timer
