Time Package – Parsing, Formatting, and Timers

Working with Time

This lesson explains the main concept clearly with beginner-friendly examples and background so you can learn why the code works.

now := time.Now()
fmt.Println(now.Format(time.RFC3339))

// Parse ISO‑8601
t, err := time.Parse(time.RFC3339, "2024-03-25T12:34:56Z")

// Timer & After
timer := time.NewTimer(2 * time.Second)
<-timer.C // blocks for 2 s

Tickers (periodic actions)

ticker := time.NewTicker(1 * time.Second)
defer ticker.Stop()
for range ticker.C {
    fmt.Println("tick")
}

Timezones

loc, _ := time.LoadLocation("America/New_York")
nyc := now.In(loc)
