This article shows you what is the basic concept of C++ time, the content is concise and easy to understand, absolutely can make your eyes bright, through the detailed introduction of this article, I hope you can get something.

There are still many operations on time in C++ programming language, which can help program developers to achieve a variety of requirements for time operation in actual programming. We can then through the introduction of this article on the basic concept of C++ time, to a preliminary interpretation of this application skills.

Keywords: UTC (World Standard time), Calendar Time (Calendar time), epoch (time Point), clock tick (clock timing Unit)

There are many noticeable problems in the operation of string in C _ + _. Recently, many netizens in the technology group have asked questions about the operation, acquisition and display of time in C++ language for many times. Next, in this article, the author will mainly introduce the use of time and date in C _ chart +.

You can have a lot of ways to manipulate and use C++ time by learning many Cmax Clipper + libraries. But before you do that, you need to understand some concepts of "time" and "date". There are mainly the following:

Coordinated Universal Time (UTC): coordinated Universal time, also known as Universal Standard time, also known as Greenwich mean time (Greenwich Mean Time,GMT). For example, the time difference between mainland China and UTC is + 8, that is, UTC+8. The United States is UTC-5.

Calendar Time: calendar time, which is expressed as the number of seconds elapsed from a standard point in time to this time. This standard time point will be different for different compilers, but for a compilation system, this standard time point is constant, and the calendar time corresponding to the time in the compilation system is measured by this standard time point, so it can be said that calendar time is "relative time", but no matter which time zone you are in, at the same time for the same standard time point, the calendar time is the same.

Epoch: point in time. The time point is an integer in the standard CCompact +, which is expressed by the number of seconds between the time at this time and the standard time point (that is, calendar time).

Clock tick: a clock timing unit (instead of calling it a clock tick). The length of time of a clock timing unit is controlled by the CPU. A clock tick is not a clock cycle of a CPU, but a basic timing unit of the Cmax plus.

We can use the time.h header file in the ANSI standard library in the C++ time operation. The methods used for the time and date defined in this header file, whether in structure definition or naming, have a clear C language style.
