Re: More count-down clock lunacy

The feed is updated every 5 seconds

I don't think so.

I request the feed every minute via a cron job. There's jitter in the timing of a cron job. However, there's definitely more than a 5 second interval between one request and the next.

I've received several instances of the exact same feed, when the requests were 1 minute apart. I'm now in the process of writing SQL to remove these duplicates because they present problems for more complex analysis. Fortunately, I had the good sense to record both the time I made the download request and the data's internal timestamp. It should not be a difficult job.
