In Go language, time packages supplies functionality for determining as well as viewing time. The Since() function in Go language holds time value and is used to evaluate the difference with the actual time. Moreover, this function is defined under the time package. Here, you need to import the “time” package in order to use these functions.
Syntax:
func Since(t Time) Duration
Here, t is the time value.
Note: This method is shortcut for time.Now().Sub(t).
Return value: It returns a duration value.
Example 1:
// Golang program to illustrate in Golang // Including main package package main // Importing fmt and time import ( "fmt"
"time"
) // Calling main func main() { // Defining time value
// of Since method
now := time .Now()
// Prints time elapse
fmt.Println( "time elapse:" ,
time .Since(now))
} |
Output:
time elapse: 210ns // Can be different at different run times
Here, time elapse between now and the current time is printed. So, it can be different at different run times.
Example 2:
// Golang program to illustrate in Golang // Including main package package main // Importing fmt and time import ( "fmt"
"time"
) // Calling main func main() { // Defining time value
// of Since method
timevalue := time .Now()
// Calling Since method
// with its parameter
Duration := time .Since(timevalue)
// Prints time elapse in nanoseconds
fmt.Println( "time elapse in nanoseconds:" ,
Duration.Nanoseconds())
} |
Output:
time elapse in nanoseconds: 351 // Can be different at different run times
