Get current time as formatted string in Go?

Question

What\'s the best way to get the current timestamp in Go and convert to string? I need both date and time in eg. YYYYMMDDhhmmss format.

Answer 1

All the other response are very miss-leading for somebody coming from google and looking for "timestamp in go"! YYYYMMDDhhmmss is not a "timestamp".

To get the "timestamp" of a date in go (number of seconds from january 1970), the correct function is .Unix(), and it really return an integer

Answer 2

As an echo to @Bactisme's response, the way one would go about retrieving the current timestamp (in milliseconds, for example) is:

msec := time.Now().UnixNano() / 1000000

Answer 3

https://golang.org/src/time/format.go specified For parsing time 15 is used for Hours, 04 is used for minutes, 05 for seconds.

For parsing Date 11, Jan, January is for months, 02, Mon, Monday for Day of the month, 2006 for year and of course MST for zone

But you can use this layout as well, which I find very simple. "Mon Jan 2 15:04:05 MST 2006"

    const layout = "Mon Jan 2 15:04:05 MST 2006"
    userTimeString := "Fri Dec 6 13:05:05 CET 2019"

    t, _ := time.Parse(layout, userTimeString)
    fmt.Println("Server: ", t.Format(time.RFC850))
    //Server:  Friday, 06-Dec-19 13:05:05 CET

    mumbai, _ := time.LoadLocation("Asia/Kolkata")
    mumbaiTime := t.In(mumbai)
    fmt.Println("Mumbai: ", mumbaiTime.Format(time.RFC850))
    //Mumbai:  Friday, 06-Dec-19 18:35:05 IST

Answer 4

Use the time.Now() function and the time.Format() method.

t := time.Now()
fmt.Println(t.Format("20060102150405"))

prints out 20110504111515, or at least it did a few minutes ago. (I'm on Eastern Daylight Time.) There are several pre-defined time formats in the constants defined in the time package.

You can use time.Now().UTC() if you'd rather have UTC than your local time zone.

Answer 5

Use the time.Now() and time.Format() functions (as time.LocalTime() doesn't exist anymore as of Go 1.0.3)

t := time.Now()
fmt.Println(t.Format("20060102150405"))

Answer 6

To answer the exact question:

import "github.com/golang/protobuf/ptypes"

Timestamp, _ = ptypes.TimestampProto(time.Now())
