Golang time conversion: How to convert timestamp to string

In Golang, time operation is one of the very common operations. Sometimes we need to convert the timestamp into a string for easy display or storage. This article will introduce how to use Golang to convert timestamps to strings and provide specific code examples.

1. Conversion of timestamps and strings

In Golang, timestamps are usually expressed in the form of integer numbers, which represent the period from January 1, 1970 to the present The number of seconds of time. Strings represent time in human-readable form, such as "2022-09-30 15:04:05".

2. Convert the timestamp to a string

To convert the timestamp to a string, you first need to use the time.Unix() function to convert the timestamp to time.Time type, and then use the time.Format() method to format time.Time into a string.

Here is a sample code to convert timestamp to string:

package main

import (
    "fmt"
    "time"
)

func main() {
    timestamp := int64(1632974400) // 假设时间戳为2021年9月30日00:00:00的时间戳
    tm := time.Unix(timestamp, 0)
    fmt.Println(tm.Format("2006-01-02 15:04:05"))
}

In this code, we convert timestamp 1632974400 to time.Time type , and format it into a string using the Format() method. The output will be "2021-09-30 00:00:00".

3. String formatting

When using the Format() method, you need to define a format string to determine the output format of the time. Among them, the number part represents the year, month, day, hour, minute and second of the time, for example:

• "2006" represents the year
• "01" represents the month
• "02" represents Date
• "15" represents the hour (24-hour format)
• "04" represents the minute
• "05" represents the second

4. Custom format string

In addition to using fixed format strings, we can also customize the formatting method as needed. For example, to output a time format similar to "2021-09-30T00:00:00Z", you can use the following code:

fmt.Println(tm.Format("2006-01-02T15:04:05Z"))

Conclusion

Through the introduction of this article, you should now know how to Timestamps are converted to strings in Golang. Remember, time operations are very common in actual development, and mastering time conversion methods can improve programming efficiency. Hope the above content is helpful to you!
