Golang is an emerging programming language, and more and more developers are beginning to learn and use it. But for beginners, some operations may not be so easy to understand. For example, set Chinese time. In this article, we will share how to set Chinese time in Golang environment.

First, we need to understand the time-related functions in Golang:

  1. func Now() Time

Now() function will return the current local time. Its return value type is the Time type. The Time type represents the time information at a certain point in time, including year, month, day, hour, minute, second, etc.

  1. func (t Time) UTC() Time

UTC() will convert the time to the time in the UTC time zone, and the time returned is still the Time type.

  1. func (t Time) Local() Time

Local() will convert the time to the time in the local time zone, and the time returned is still the Time type.

Both the UTC() and Local() methods return the Time type. The difference between them lies in the different time zones for conversion.

Next, let’s introduce how to set the Chinese time.

We can get the current time through the following code:

nowTime := time.Now()
fmt.Println(nowTime)
Copy after login

The running result may be like this:

2021-10-20 23:04:42.64616 +0800 CST m=+0.000102137
Copy after login

You can see that the result contains time zone information, assuming we want To convert it to Chinese time, you need to perform the following operations:

location, err := time.LoadLocation("Asia/Shanghai")
if err != nil {
    panic(err)
}
chinaTime := nowTime.In(location)
fmt.Println(chinaTime)
Copy after login

In the code, the time.LoadLocation() function specifies the time zone to be converted, and returns the Location type, which contains time zone related information. Moreover, we use the In() method of the Time type to convert the current time to the time zone we specify, and the time returned is also a Time type.

Execute the above code to successfully convert the current time to Chinese time. The results are as follows:

2021-10-20 23:04:42.64616 CST
Copy after login

We can easily perform time conversion by setting the time zone, but we need to pay attention to Yes, the time zone setting needs to be done according to the actual situation. Especially in cross-time zone application scenarios, be particularly careful.

To summarize, the code for setting Chinese time is as follows:

nowTime := time.Now()
fmt.Println(nowTime)

location, err := time.LoadLocation("Asia/Shanghai")
if err != nil {
    panic(err)
}
chinaTime := nowTime.In(location)
fmt.Println(chinaTime)
Copy after login

The above is the content of this article. I hope it can help readers set Chinese time in the Golang environment. If you have any other questions, please leave them in the comment area.
