Issue Summary

Both the GitHub repo and the documentations above including the following code which uses a datetime object:

# Convert "seconds from now" into an rfc3339 datetime string.
    timestamp = datetime.datetime.utcnow() + datetime.timedelta(seconds=in_seconds)

But this results in the following error:

TypeError: Parameter to MergeFrom() must be instance of same class: expected google.protobuf.Timestamp got datetime.datetime.

To fix this, users must use the Timestamp object, as found in this GitHub issue [1]:

d = datetime.datetime.utcnow() + datetime.timedelta(seconds=in_seconds) 
  
 # Create Timestamp protobuf. 
 timestamp = timestamp_pb2.Timestamp() 
 timestamp.FromDatetime(d) 

Documentation needs to be updated to reflect the correct object type.

Side Note: Customer created a GH issue detailing the steps they used to reproduce this error. See here [2].
