millisecond counter

There is no millisecond unit of time in a Linux shell, and only seconds and nanoseconds are actually sufficient, since the unit range of nanoseconds is (000000000). 999999999), so the nanosecond is also available from nanoseconds to milliseconds.current= ' Date ' +%y-%m-%d%h:%m:%s "' #获取当前时间, Example: 2015-03-11 12:33:41 timestamp= ' date-d ' $current ' +%s ' #将curr Ent converted to timestamp, accurate to seconds currenttimestamp=$ ((timestamp+ ' Date

Lua's own time functions can only be accurate to seconds. In order to count the time of millisecond precision, you can use Luasocket. Download Address Http://files.luaforge.net/releases/luasocket/luasocket When compiling the installation, you may need to specify the LUAINC variable as your LUA path in the config file in the source package root directory. Copy Code code as follows: Local socket = require "socket" Local T0 = Socket.gettime (

Design a hit counter which counts the number of hits received in the past 5 minutes.Each function accepts a timestamp parameter (in seconds granularity) and your may assume that calls is being made to the S Ystem in chronological order (ie, the timestamp is monotonically increasing). Assume the earliest timestamp starts at 1.It is possible this several hits arrive roughly at the same time.Example:Follow up:What if the number of hits per second could i

Then, we should test whether the file can be opened. Our counter often uses the inventory file for implementation. The file written by the counter is count.txt under the current directory, and then we should test whether the file can be opened. Script ec (2); script Example of page counters based on file systems $ Countfile = "num.txt ";// Define that the file written by the

Counter-clockwise print matrix, counter-clockwise Matrix The life of graduate students is boring. Recently I want to go out and look for internships. I will review the data structure. I did not review the data structure in my freshman year. I was despised during the interview. When I saw a senior student, it should be the test question of Kingsoft: To a matrix, print the matrix

JavaScript is a counter method based on setTimeout. It is a javascript counter. The example in this article describes how to count JavaScript Based on setTimeout. Share it with you for your reference. The specific implementation method is as follows: Var count = 0; var timer; var timerOn = false; function timedCount () {count ++; timer = setTimeout (function () {timedCount () }, 1000 );} function doTimer

The examples in this article describe the JavaScript millisecond usage. Share to everyone for your reference. Specifically as follows: The number of milliseconds is the number of milliseconds between the specified date and time from Midnight January 1, 1970 (GMT time). 1, the number of milliseconds of the current system time var myData = new Date (); var times = Mydata.gettime ();//The number of milliseconds in the current time 2, the numbe

This article illustrates the JS millisecond countdown to the results of the code, sharing for everyone to reference, the specific content as follows Effect Chart: Implementation function: Call a function, pass in the ID of the HTML element, and a cutoff time (Unix timestamp), print out the countdown to the current to the cutoff time in the HTML element, accurate to milliseconds; The effect chart is as follows: How do I use this function?

Millisecond conversion to date SELECT To_char (1406538765000/1000) + to_date (' 1970-01-01 08:00:00 ', ' yyyy-mm-dd HH:MI:SS '), ' yyyy-mm -dd HH24:MI:SS ') as CDATE from DUAL; Date conversion milliseconds SELECT To_number (to_date (' 2014-07-28 17:12:45 ', ' yyyy-mm-dd HH24:MI:SS ')- to_date (' 1970-01-01 8:0:0 ', ' Yyyy-mm-dd HH24:MI:SS ')) * * * 1000 from DUAL; Get System Current Time Select To_char (sysdate, ' Yyyy-mm-dd h

A multi-thread counter and multi-thread counter I recently read "deep understanding of parallel programming", which is C. The first 200 pages seem to be a general idea. As mentioned above, there is a counter problem, so I want to implement it in java. Problems encountered:1. If there are only two threads, one read and one write, do you need to lock this resource?

Improve and optimize cs' anti-terrorism image effects/QualityNonsense: Anti-Terrorism 2!But counter-terrorism 2 has changed a lot, without the pleasure of CS. Our CS fans only use cs1.6.Cs1.6 releases zero-point action condition zeroHis Screen Effect is much better than that of cs1.6, and CS is very pleasant.Recently I found out how to improve the zero-point action picture-d3d mode. Why does CS2 not use the old OpenGL.However, there are many bugs in t

The Active server Pager (Dynamic Servers home page, abbreviated as ASP) can easily implement page counter functionality by reading and writing server files, combining the script language (VBScript or JScript) and HTML code. Now popular ASP textbooks and ASP tutorials on the network have talked about the design of ASP counters, but are too simple, such as not mention how to implement counter script and the s
