clockview

Linux, the commands for clock viewing and setting are mainly date, hwclock, and clock. Among them, clock and hwclock usage is similar, only use one on the line, except that the clock command supports the Alpha hardware system in addition to the x86 hardware system. 1.

Linux system time is sometimes not synchronized with hardware timeLinux Clock is divided into System Clock and Real Time Clock (RTC. The system clock is the current Linux Kernel clock, and the hardware clock is the battery-powered clock on the motherboard. This hardware clock can be set in the BIOS. When Linux is started, the hardware clock reads the system clock settings, and then the system clock runs independently of the hardware.All commands (including functions) in Linux use the system cloc

It can not only update the system clock from the NTP server, but also calculate the clock frequency and manage the system time accordingly. 　　 With clock speed, you only need to occasionally synchronize the NTP server after the initial configuration; this occasional time can even be once a year. 　　 First, download the clock speed from the network for compilat

servers at NIST, China National Timing Center and China Education Network are at this level. Stratum = 2 of the NTP server is synchronized with the stratum = 1 server, the performance is slightly worse, but the accuracy is also in the order of milliseconds, so there is no difference. Next to each synchronization level, Stratum adds one.Windows 2000 starts with a service that automatically synchronizes time. On Windows XP, the open time setting has a network pair setting. The default is once per

1. Overview This article is mainly about how to customize a time clock, through simple exercises can be a simple study of Android in the custom view of some of the common drawing techniques to optimize the Android graphics operation. To start with, look at the effect we need to achieve: When we see this effect there should be some thinking in mind, we should break it down into the following steps:1. Instrument panel (Round)2, tick marks (long medium short)3, tick value (1-12)4. Pointer (time
