small context manager to log timing on http request (or whatever)

gistfile1.py

timing_logger = logging.getLogger('something')

@contextmanager
def timing(name):
      t1 = datetime.now()
      try:
          yield
      finally:
          t1 = datetime.now() - t1
          t1 = t1.seconds + t1.microseconds/1e6
          timing_logger.info(name , exc_info=sys.exc_info(), extra={'data': {
              'seconds': "%.2f" % t1,
              'when': datetime.now()
          }})
