ptp clock

1. There are two types of clocks under Linux:1.1 Real Clock RTCThe "Real Time Clock", which is powered by the onboard battery, is also called the RTC or the CMOS clock, the hardware clock. When the operating system shuts down, use this to record the time, but for the running system is not the time.1.2 System

#filename my little alarm clock.Import timeImport SysImport WinSoundA=time.ctime ()Print ("***************** Pro is Now", A, "**********************")Print ("*********************** welcome you to use Shup DIY alarm Clock applet ***********************")Hour1=int (Input ("*****************", enter the hour you want to set the alarm (for example, 10): "))Minutes=int (Input ("**************** Pro, please enter the minutes to set the alarm (e.g. 20):"))i

Linux has 2 clocks, a hardware clock, and a system clock.The date command sees the system timeHwclock saw hardware time.Hwclock-r #读取硬件时间 (-R can be omitted)Hwclock-w #将系统时间写入到硬件Hwclock-s #将硬件时间写入到系统#下面为如何配置网络ntpdate更新Yum install-y ntpntpdate time.windows.comhwclock-w# can be written directly to a timed task to ensure system time is accurate. echo "*/10 * * * * */usr/sbin/ntpdatetime.windows.com>/dev/null 2>1" >>/var/spool/cron/rootecho "/sbin/ Hwcloc

Analysis: The clock replacement algorithm is realized by using cyclic queue. In the operating system, the textbook explains this.Code implementation:#include using namespace Std;typedef struct NUMBERNODE{int *data;BOOL *ask;//Visit question mark}numnode;typedef struct NODE{Numnode Numnode;int maxsize;int rear;int front;}queue;queue* Create ();void push (queue *);void Pop (queue *);int Turnyemian (queue *myque,int Telem);queue* Create (){Queue *myque=n

Pure JS code to make the Web clock special effects, need the code farmers can take a look. For everyone to make a reference. Above this pure JS code to make the Web clock special effects "attached example" is a small series to share all the content, hope to give you a reference, but also hope that we support the cloud-dwelling community.

A tutorial on designing a clock theme icon for users of Photoshop software. Tutorial Sharing: Final effect: The background is nothing to say, is to make a gradient, set the foreground color for #f8efe0, with rounded rectangle tool to draw a rounded rectangle, this is our main body. Adds a layer style to the rounded rectangle. Tips, the gradient overlay style in the layer blending mode is superimposed

First, look at the effect of the alarm clock page Features to implement: 1: Turning pictures According to weather conditions change 2: Turning time can be set, the end of rotation, alarm sound on the end 3: Aperture Color Gradient effect Directly on the code: Package Com.yuekong.sirius.extension.customview; Import Android.animation.Animator; Import Android.animation.ValueAnimator; Import Android.content.Context; Import Android.content.

Meaning There is a strange clock only minutes of the pointer, a start to stop at the S branch, and then now have D-type coins, put into the clock will be d*s step, asked to need a few such coins. Analysis: The topic is not difficult, read understand should know is the use of the mark, because it is not difficult, I started without looking at the topic on the brush to write well, submitted WA, look

This article illustrates the JavaScript background clock implementation method. Share to everyone for your reference. Specifically as follows: Here is the entire code for this effect. [Better start from an empty page] Description: The location of the clock display requires you to correct the Top,left parameters to determine. The top represents the pixel value of the layer distance from the display

To the users of Photoshop software to explain the detailed interpretation of the retro style of the time to share the photos of the clock Tower tutorial. Tutorial Sharing: The use of retro-style photos is very wide, still life, scenery, people, architecture and so can be used in this way to express the sense of age and history. Today for you to recommend a PS out of age and historical sense of retro style photos, quite practical tu

Absrtact: In practical application, the clock of each workstation in client/server architecture is often required to keep synchronized with the server clock; This paper illustrates a solution based on Sybase database and PowerBuilder development tool. First, the preface PowerBuilder through the Data window object, the database can be operated conveniently and directly, so it has become the first Choice de

1. Clock domain: MSYS, Dsys, PSYS(1) because the s5pv210 clock system is more complex, the internal peripheral module too many, so the entire internal clock divided into 3 chunks, called 3 domains.(2) MSYS:CPU (Cortex-a8 Core), DRAM controllers (DMC0 and DMC1), Iramirom(3) Dsys: All the modules related to video display, codec, etc.(4) PSYS: And the internal vario

The Android System alarm timer function framework, in general, is to use the database to store timing data, there is a state manager to manage these timing status of the trigger and update. In the andriod system to achieve the timing function, the end is to use the system provided by the Alarmmanager, just when a timed completion of how to continue processing, or the middle how to update the timing or state, such as the alarm clock such an application

The modern CPU and motherboard have power-saving technologies, which automatically reduce the frequency when the CPU is low-load. If you need to temporarily set the clock speed and working mode, you can use cpufreq to manually adjust it. This mode will expire after restart. if you need to adjust it for a long time, modify/etc/sysconfig/cpuspeed. 1. check whether the kernel has been loaded by running the lsmod | grep quot; acpi_cpufreq quot; SSH comm
