Time

Context

The time package provides functions for measuring and displaying time. Use time.Now() for current time, time.Sleep for delays, and time.Timer for scheduled events.

Example

Get current time, add durations, and measure execution.

Code example

package main

import (
    "fmt"
    "time"
)

func main() {
    now := time.Now()
    fmt.Println("Now:", now)

    later := now.Add(2 * time.Hour)
    fmt.Println("In 2 hours:", later)

    start := time.Now()
    time.Sleep(100 * time.Millisecond)
    elapsed := time.Since(start)
    fmt.Println("Elapsed:", elapsed)
}

Output (example)

Now: 2025-03-15 10:30:00.123456789 +0000 UTC
In 2 hours: 2025-03-15 12:30:00.123456789 +0000 UTC
Elapsed: 100.123456ms
