As probably many of you geeks already know, today the epoch counter (AKA unix timestamp) will reach the value 1234567890, which is cool I guess because it is in the order the keys are on your keyboard. You can find a countdown here. You can use the following perl snippet to find out when the event will occur in your timezone (apparently the timestamp is to be interpreted in UTC/GMT, which I didn't know):
perl -e 'print scalar localtime(1234567890),"\n";'
