Golang time.Time.Nanosecond()函数用法和示例
在Go语言中,time包提供了确定和查看时间的功能。Time.Nanosecond()函数在Go语言中用于查找“t”提供的秒内纳秒偏移量,范围为[0,999999999]。此外,该函数在time包中定义。因此你需要导入“time”包才能使用这些功能。
语法:
func (t Time) Nanosecond() int
这里,“t”是指定的时间。
返回值: 返回“t”所提供的秒内的纳秒偏移量。
示例 1:
// Golang program to illustrate the usage of
// Time.Nanosecond() function
// Including main package
package main
// Importing fmt and time
import "fmt"
import "time"
// Calling main
func main() {
// Declaring t in UTC
t := time.Date(2017, 23, 5, 11,
51, 04, 30, time.UTC)
// Calling Nanosecond method
nano := t.Nanosecond()
// Prints nanoseconds as specified
fmt.Printf("The stated nanoseconds "+
"specified is: %v\n", nano)
}
输出:
The stated nanoseconds specified is: 30
示例 2:
// Golang program to illustrate the usage of
// Time.Nanosecond() function
// Including main package
package main
// Importing fmt and time
import "fmt"
import "time"
// Calling main
func main() {
// Declaring t in UTC
t := time.Date(2017, 34, 56, 78,
87, 97, 687678678685757, time.UTC)
// Calling Nanosecond method
nano := t.Nanosecond()
// Prints nanoseconds as specified
fmt.Printf("The stated nanoseconds "+
"specified is: %v\n", nano)
}
输出:
The stated nanoseconds specified is: 678685757
这里,上述代码中指定的纳秒超出了通常范围,但在转换时被规范化。
