Recording the total time taken for running a spider in scrapy

I am using scrapy to scrap a site

I had written a spider and fetched all the items from the page and saved to a csv file, and now i want to save the total execution time taken by scrapy to run the spider file, actually after spider execution is completed and when we have at at terminal it will display some results like starttime, endtime and so on …. so now in my program i need to calculate the total time taken by scrapy to run the spider and storing the total time some where….

Can anyone let me now how to do this through an example……..

Thanks in advance………..

Answer

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)
