Recording the total time taken for running a spider in scrapy

This could be useful:

from scrapy.xlib.pydispatch import dispatcher
from scrapy import signals
from scrapy.stats import stats
from datetime import datetime

def handle_spider_closed(spider, reason):
    print 'Spider closed:', spider.name, stats.get_stats(spider)
    print 'Work time:', datetime.now() - stats.get_stats(spider)['start_time']


dispatcher.connect(handle_spider_closed, signals.spider_closed)
