How do I get the current timestamp in Go?

问题:

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.

回答1:

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.

回答2:

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))
}

回答3:

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

回答4:

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)

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

To answer the exact question:

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

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