Uh... this sounds like an urban legend to me. The dateline appears on maps, not in the air. I can't see how it would have any effect whatsoever.

This was initially reported about a week ago. They did indeed return to Hawaii, but news reports of the time just said "software glitch".

I write navigation software for a living, and I can certainly see how the issue came up. It's not the "date" part that's the problem it's crossing from latitude -190 to +190. Kind of like a Y2K issue, except this one happened for real. Basically any map they had would have a reversal of sequence within the same map, which could cause any number of issues.

The part that worries me is that they lost so many sub-systems, like fuel, etc. Or perhaps they merely lost their display of those indications, while the hardware functioned merrily on it's own.

You do what for a living?

East-west involves changing longitude.
