Use the time.Split function to parse the string into a time format and return the date and time parts

In the Go language, processing time and dates is a common task. The time package provides rich functionality to handle time and date operations. One of the commonly used functions is time.Parse, which parses strings into time format. However, in some cases we only need the date or time part, not the complete time. At this time, we can use the time.Split function to achieve this purpose.

The following is a sample code that demonstrates how to use the time.Split function to parse a string into a time format and return the date and time parts:

package main

import (
    "fmt"
    "strings"
    "time"
)

func main() {
    str := "2021-01-01T12:30:45"
    date, time := splitDateTime(str)
    fmt.Println("Date:", date)
    fmt.Println("Time:", time)
}

func splitDateTime(dateTimeStr string) (string, string) {
    splitStrings := strings.Split(dateTimeStr, "T")
    return splitStrings[0], splitStrings[1]
}

In this sample code, we define A splitDateTime function that receives a string representing a date and time as parameters. First, we use the strings.Split function to split the string according to "T" and obtain a string slice splitStrings. splitStrings[0] represents the date part, splitStrings[1] represents the time part. Finally, we return the date part and time part as multiple return values.

In the main function, we call the splitsDateTime function and pass in a sample string "2021-01-01T12:30:45". We then print out the returned date part and time part.

Run the above code, the output is as follows:

Date: 2021-01-01
Time: 12:30:45

You can see that the string is successfully parsed into the date and time parts, and the result is correctly output.

By using the time.Split function, we can easily parse the string into time format and obtain the date and time parts. This is useful when working with time and date related tasks such as log analysis, statistics, etc. At the same time, this also demonstrates the powerful string processing and time processing capabilities of the Go language.
