time format converted to strftime default format

In the wikipedia entry for Common Log Format, the strftime format is given as:

[10/Oct/2000:13:55:36 -0700] is the date, time, and time zone that the request was received, by default in strftime format %d/%b/%Y:%H:%M:%S %z.

When I try using the time.Format function:

package main

import (
    "fmt"
    "time"
)

func main() {
    t, _ := time.Parse(time.UnixDate, "Tue Oct 10 13:55:36 PDT 2000")
    fmt.Println(time.Time(t).Format("01/Feb/2006:15:04:05 -0700"))
}

I get the output [10/Feb/2000:13:55:36 +0000], while I was expecting [10/Oct/2000:13:55:36 -0700] (per Wikipedia). What is wrong with my formatting?

I checked that day was a Tuesday and the time zone was -7h (PDT) for that date.

For the Format layout, Jan not Feb. For example,

package main

import (
    "fmt"
    "time"
)

func main() {
    t, err := time.Parse(time.UnixDate, "Tue Oct 10 13:55:36 PDT 2000")
    if err != nil {
        fmt.Println(err)
        return
    }
    fmt.Println(time.Time(t).Format("01/Jan/2006:15:04:05 -0700"))
}

Output:

10/Oct/2000:13:55:36 +0000

Also, for the time zone, use ParseInLocation,

package main

import (
    "fmt"
    "time"
)

func main() {
    loc, err := time.LoadLocation("America/Los_Angeles")
    if err != nil {
        fmt.Println(err)
        return
    }
    t, err := time.ParseInLocation(time.UnixDate, "Tue Oct 10 13:55:36 PDT 2000", loc)
    if err != nil {
        fmt.Println(err)
        return
    }
    fmt.Println(t)
    fmt.Println(time.Time(t).Format("01/Jan/2006:15:04:05 -0700"))
}

Output:

2000-10-10 13:55:36 -0700 PDT
10/Oct/2000:13:55:36 -0700
