Go by Example: Time Formatting / Parsing #431

Closed cllgeek closed 2 years ago

cllgeek commented 2 years ago

the code of example less something: , e = time.Parse(ansic, "8:41PM") should be , e := time.Parse(ansic, "8:41PM")

I think the current example is working as intended. Can you clarify what the problem is?

I ran the following code:

package main

import (
    "fmt"
    "time"
)

func main() {
    p := fmt.Println

    t := time.Now()
    p(t.Format(time.RFC3339))

    t1, e := time.Parse(
        time.RFC3339,
        "2012-11-01T22:08:41+00:00")
    p(t1)

    p(t.Format("3:04PM"))
    p(t.Format("Mon Jan _2 15:04:05 2006"))
    p(t.Format("2006-01-02T15:04:05.999999-07:00"))
    form := "3 04 PM"
    t2, e := time.Parse(form, "8 41 PM")
    p(t2)

    fmt.Printf("%d-%02d-%02dT%02d:%02d:%02d-00:00\n",
        t.Year(), t.Month(), t.Day(),
        t.Hour(), t.Minute(), t.Second())

    ansic := "Mon Jan _2 15:04:05 2006"
    _, e = time.Parse(ansic, "8:41PM")
    p(e)
}

And got the following output:

2022-06-27T15:11:43-06:00
2012-11-01 22:08:41 +0000 +0000
3:11PM

0000-01-01 20:41:00 +0000 UTC
2022-06-27T15:11:43-00:00
parsing time "8:41PM" as "Mon Jan _2 15:04:05 2006": cannot parse "8:41PM" as "Mon"

I see no issues with this, it seems to be working. Maybe @cllgeek was talking about not using := in that assignment? It doesn't break the example though.
