Convert UTC string to time object

Solution 1:

Most likely you used a wrong layout, and you didn't check the returned error.

The layout must be this date/time, in the format your input time is:

Mon Jan 2 15:04:05 -0700 MST 2006

See this working code:

layout := "2006-01-02 15:04:05 -0700 MST"
t, err := time.Parse(layout, "2014-11-17 23:02:03 +0000 UTC")
fmt.Println(t, err)

Output (try it on the Go Playground):

2014-11-17 23:02:03 +0000 UTC <nil>

EDIT:

In your question you included a + sign in your input time (as part of the zone offset), but you have error with times of other formats.

Time.String() uses the following format string:

"2006-01-02 15:04:05.999999999 -0700 MST"

So either use this to parse the times, or use Time.Format() to produce your string representations where you can specify the layout, so you can use the same layout to parse the time strings.

2nd round:

You're including your time strings in URLs. The + sign is a special character in URL encoding: it denotes the space. So the + gets converted to space (and so it vanishes from your time string). Use proper URL encoding! Check out the net/url package, and this example.

Solution 2:

Didn't see this yet but for those that don't know the formats, time has the formats builtin as constants. so you can reference them when parsing or formating.

time.Parse(time.RFC3339, <your time.Time object here>)
<time.Time object>.Format(time.RFC3339) //or other type of formats

Here they are for reference

ANSIC       = "Mon Jan _2 15:04:05 2006"
UnixDate    = "Mon Jan _2 15:04:05 MST 2006"
RubyDate    = "Mon Jan 02 15:04:05 -0700 2006"
RFC822      = "02 Jan 06 15:04 MST"
RFC822Z     = "02 Jan 06 15:04 -0700" // RFC822 with numeric zone
RFC850      = "Monday, 02-Jan-06 15:04:05 MST"
RFC1123     = "Mon, 02 Jan 2006 15:04:05 MST"
RFC1123Z    = "Mon, 02 Jan 2006 15:04:05 -0700" // RFC1123 with numeric zone
RFC3339     = "2006-01-02T15:04:05Z07:00"
RFC3339Nano = "2006-01-02T15:04:05.999999999Z07:00"
Kitchen     = "3:04PM"

Solution 3:

You are likely using the wrong layout. As explained in time.Parse, you need to specify a layout that helps Go to understand how the date passed as input is formatted.

There are predefined layouts (like the ones you were using), but none matches your input. Hence you need to define a custom layout.

A layout uses the following date as reference:

Mon Jan 2 15:04:05 MST 2006

The layout is nothing else that a representation of that date, that matches the representation of your input:

t, err := time.Parse("2006-01-02 15:04:05 -0700 MST", "2014-11-17 23:02:03 +0000 UTC")

Also remember to check err for errors. It's likely your attempts returned an error, but you didn't check it.

package main

import (
    "fmt"
    "log"
    "time"
)

func main() {
    t, err := time.Parse("2006-01-02 15:04:05 -0700 UTC", "2014-11-17 23:02:03 +0000 UTC")
    if err != nil {
        log.Fatalln(err)
    }
    fmt.Println(t)
}
