Golang: How to Convert time.Time to a Protobuf Timestamp?

Question

I have a time.Time variable in Golang 10-30 00:49:07.1236 that needs to be converted to a Go Protobuf timestamp.Timestamp. Any idea on what functions can be used to accomplish this? Or am I looking at this from the wrong angle?

Recommend using godoc or going to pkg.go.dev to read the documentation for the libraries you are using. For example, go to pkg.go.dev/google.golang.org/protobuf/types/known/… – Proliferous

Answer 1

See New and Timestamp.AsTime in timestamppb

These support conversion to/from time.Time and Timestamp

Answer 2

Try using the timestamppb.New

like this:

newTimeStamp:=timestamppb.New(your_time)

Answer 3

Instead of using like this

timeNow := time.Now()
timestamp := timestamppb.Timestamp{
    Seconds: timeNow.Unix(),
    Nanos:   int32(timeNow.Nanosecond()),
} 

try this :

timestamppb.New(time.Now())

Answer 4

Below code will give convert time.Time to protobuf timestamppb format

import "google.golang.org/protobuf/types/known/timestamppb"
timeNow := time.Now()
timestamp := timestamppb.Timestamp{
    Seconds: timeNow.Unix(),
    Nanos:   int32(timeNow.Nanosecond()),
}
fmt.Printf("as timestamp %+v\n", timestamp)
fmt.Printf("as time.Time %+v\n", timestamp.AsTime().Local())

Output looks like this:

as timestamp {state:{NoUnkeyedLiterals:{} DoNotCompare:[] DoNotCopy:[] atomicMessageInfo:<nil>} sizeCache:0 unknownFields:[] Seconds:1694773177 Nanos:777135000}
as time.Time 2023-09-15 15:49:37.777135 +0530 IST
