Wow, when they said “archive,” they really meant it! 🙂

While SharpReader is the best aggregator I’ve tried for Windows, it does have problems with dates from time to time — sometimes articles will be stamped with the time they were downloaded instead of the time they were posted.

And I suspect in this case, it’s missing a date. (In UNIX, and as a result across most of the Internet, time is measured in seconds since GMT midnight January 1, 1970. If you somehow end up with a time of -1, this is what you get.)
