Get current date & time

now := time.Now()
// get current timestamp
ts := now.Unix()
// get current timestamp nano
ts := now.UnixNano()

Format

now.Format("Monday January 2, 2006")
now.Format("01/02/2006 15:04:05")
now.Format("01/02/2006 3PM")

Timezone

tz, _ := time.LoadLocation("America/Chicago")
ccgTime := t.In(tz)
fmt.Println("Chicago Time:", ccgTime)

Parse Time

timeToParse := "2019-02-15T07:33-05:00"
parsed, err := time.Parse("2006-01-02T15:04-07:00", timeToParse)
if err != nil {
    panic(err)
}
fmt.Println(parsed)

// parseInLocation will carry timezone info after parsing
parsed2, _ := time.ParseInLocation(
                        "2/1/2006 3:04 PM ", 
                        "31/7/2015 1:25 AM ", 
                        time.Local)
fmt.Println(parsed2)

Time Diff

start := time.Now()
end := time.Now()
duration := end.Sub(start)

Add date & time

// add 1 year 2 months and 3 days
fmt.Println(now.AddDate(1, 2, 3))
fmt.Println(now.Add(5 * time.Hour))
