Colleague at work brought this up today. I suggested she touch every file on her disk (Yes, I concede this wouldn't "work" as such).
That was in this month's Atomic mag too. Local time for me says it will be Saturday the 14th at 10:31:30 (AM). Another geeky thing the same article points out to consider is that Linux (and every other variation of Unix) never suffered from the Y2K Millennium Bug, but they will on Tuesday the 19th January 2038 at 03:14:07 - the 32-bit integer used by Unix variants to store the time will run out of space and will wrap back to zero, making clocks show the epoch (January 1st 1970). Though by that time we should have all switched to 64-bit and will have another 292 billion years of headroom before it wraps around again.
