Central Earth space (Cartesian) coordinate system-defined as the origin O and the earth center coincidence, the Z axis points to the earth's Arctic, the X axis points to the intersection of the Greenwich Meridian and the Earth's equator, the Y axis perpendicular to the XOZ plane constitute the right hand coordinate system. The Cartesian coordinate system of the central Earth space is a type of coordinate system, which is used to describe the position

Before you introduce the Date object, first understand some knowledge about dates and times. For example, leap years, UTC, and so on. Having a closer look at these will help you better understand the date objects in JavaScript. This article will introduce the basics of JavaScript about date and time

strings that conform to the RFC2822/IETF date syntax (RFC2822 section 3.3), such as "Mon, DEC 1995 13:30:00 GMT". This method can understand the abbreviation of the continental time zone, but for more general use time zone offsets, such as "Mon 1995 13:30:00 +0430" (4 hours and 30 minutes to the east of Greenwich Meridian). If no time zone is specified, the local time zone is used by default.
GMT and UTC are considered equal. If the RFC2822 section
In the Linux system, we can use the "hostname" command to view the host name, using "Hostname-i" to view the corresponding IP address of the machine name. To modify this host name, you need to modify the two configuration files.
First, modify the "/etc/sysconfig/network" file to change the "hostname=******" line to the desired;
The code is as follows
Copy Code
