'How do i create a protobuf3 Timestamp in python?

I see that there is a Timestamp object but it doesn't seem to work. Using Python 3.6

$ pip install protobuf3

In python:

from google.protobuf.timestamp_pb2 import Timestamp
timestamp = Timestamp()
timestamp.GetCurrentTime()

Nothing is returned. What am I doing wrong?

ARRGGG I think there was a virtual env problem. It works now!

Python 3.6.4 (v3.6.4:d48eceb, Dec 19 2017, 06:54:40) [MSC v.1900 64 bit (AMD64)] on win32
>>> from google.protobuf.timestamp_pb2 import Timestamp
>>> timestamp = Timestamp()
>>> timestamp.GetCurrentTime()
>>> print(timestamp)
seconds: 1521497361
nanos: 600455000

>>>timestamp
seconds: 1521497361
nanos: 600455000

The only two args of constructing a protobuf Timestamp are seconds and nanos. They are defined as the seconds from the Epoch (1970-01-01 00:00:00). So we can do:

import datetime
from google.protobuf.timestamp_pb2 import Timestamp

t = datetime.datetime.now().timestamp()
seconds = int(t)
nanos = int(t % 1 * 1e9)

proto_timestamp = Timestamp(seconds=seconds, nanos=nanos)

Solution 3:^[3]

Simple example:

message Data {
    google.protobuf.Timestamp tstamp = 1;
}

setting value:

message.tstamp.FromDatetime(datetime.datetime.now())

printing received message:

tstamp {
    seconds: 1648070801
    nanos: 661005000
}

timestamp.GetCurrentTime()

Actually this method fills in the current time rather than getting the current time.
