time.Time.Before() Function in Golang With Examples
In Go language, time packages supplies functionality for determining as well as viewing time. The Time.Before() function in Go language is used to check if the stated time instant t is before the stated u or not. 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 (t Time) Before(u Time) bool
Here, “t” is the stated time and “u” is the time that is present as an argument in the Before() method.
Return Value: It returns true if “t” is present before “u” else it returns false.
Example 1:
// Golang program to illustrate the usage of // Time.Before() function // Including main package package main // Importing fmt and time import "fmt"import "time" // Calling main func main() { // Declaring t and u in UTC t := time.Date(2019, 0, 0, 0, 0, 0, 0, time.UTC) u := time.Date(2020, 0, 0, 0, 0, 0, 0, time.UTC) // Calling Before method res := t.Before(u) // Prints output fmt.Printf("%v", res) } |
