You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: object.go
    path of file: ./repos/rclone/backend/storj
    
    the code of the file until where you have to start completion: //go:build !plan9
// +build !plan9

package storj

import (
	"context"
	"errors"
	"io"
	"path"
	"time"

	"github.com/rclone/rclone/fs"
	"github.com/rclone/rclone/fs/hash"
	"github.com/rclone/rclone/lib/bucket"
	"golan
    
func newObjectFromUplink(f *Fs, relative string, object *uplink.Object) *Object {
	// Attempt to use the modified time from the metadata. Otherwise
	// fallback to the server time.
	modified := object.System.Created

	if modifiedStr, ok := object.Custom["rclone:mtime"]; ok {
		var err error

		modified, err = time.Parse(time.RFC3339Nano, modifiedStr)
		if err != nil {
			modified = object.System.Created
		}
	}

	bucketName, _ := bucket.Split(path.Join(f.root, relative))

	return &Object{
		fs: f,

		absolute: norm.NFC.String(bucketName + "/" + object.Key),

		size:     object.System.ContentLength,
		created:  object.System.Created,
		modified: modified,
	}
