Time conversion from string in golang

I'm trying to convert a time/date crawled from a NOAA observation from UTC to Pacific Time. The raw data is formatted as a fixed width space delimited string that I convert into an array of strings via strings.Field.

The raw data looks like:

2015 11 11 16 50

It is stored as: 

data[0:5]

Note that data has additional observations that are used elsewhere in the program. How can this be converted to Pacific time such that it will be correct year round, including daylight savings changes? I would eventually like to print it out in RFC822 format (i.e. "02 Jan 06 15:04 PST").

You can parse your raw data directly to a time in UTC using time.Parse and Go's reference time (https://golang.org/pkg/time/#pkg-constants), and then load a PST location and convert the time to that location. It can then be formatted as you wish, e.g.:

func main() {
    t, err := time.Parse("2006 01 02 15 04", "2015 11 11 16 50")
    fmt.Println(t, err)

    loc, err := time.LoadLocation("America/Los_Angeles")
    fmt.Println(loc, err)

    t = t.In(loc)
    fmt.Println(t.Format(time.RFC822))
}
