informs me that time_t (the number of seconds elapsed since Jan. 1, 1970, the standard measure of time under Unix) will be 1234567890 on Feb. 13 2009, at 18:31:30 EST, or 23:31:30 UTC.
Back on Sep. 8, 2001, when time_t rolled over to 10 digits, we were braced for a mini-Y2K. I don’t expect anything to happen this time, except for a bunch of Unix geeks hoisting beers.
