Get current time as formatted string in Go?
TimestampGoTimestamp Problem Overview
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.
Timestamp Solutions
Solution 1 - Timestamp
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.
Solution 2 - Timestamp
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
Solution 3 - Timestamp
For readability, best to use the RFC constants in the time package (me thinks)
import "fmt"
import "time"
func main() {
fmt.Println(time.Now().Format(time.RFC850))
}
Solution 4 - Timestamp
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"))
Online demo (with date fixed in the past in the playground, never mind)
Solution 5 - Timestamp
Find more info in this post: Get current date and time in various format in golang
This is a taste of the different formats that you'll find in the previous post:
Solution 6 - Timestamp
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

Solution 7 - Timestamp
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
Solution 8 - Timestamp
You can simply use like strconv.Itoa(int(time.Now().Unix()))
Solution 9 - Timestamp
To answer the exact question:
import "github.com/golang/protobuf/ptypes"
Timestamp, _ = ptypes.TimestampProto(time.Now())
