Wow, keeping up this theme of powers of 10 milestones, (kirk10k (days), kermitcar50k (miles) or figure out your own milestones here) Unix turns 1,000,000,000 seconds old today. According to
September 8, 2001
perl -e 'print scalar localtime 1e9';
it's at 9:46 tonight, Eastern time.
This matters to geeks, because the standard Unix time stamp is the number of seconds since January 1, 1970, GMT, and it shows up often. Actually there may be some minor Y2K-like effects on various systems that store that timestamp as a 9-digit number, or assume you can sort the timestamp alphabetically. (Which was an assumption that worked from March 3, 1973 'til today.)

Finally, wrapping up today's theme of Time: Man, I've been through some long concerts before but this one takes the cake.
