Re: PHP 5.1.2 segfaults in get_timezone_info

Ok, I'm not sure what /etc/localtime was but when I copied over /usr/share/zoneinfo/America/New_York to /etc/localtime the problem went away and things are working gloriously-well. Perhaps just a note for the future that if somehow the OS didn't setup the timezone properly, PHP should default to something rather than segfaulting.
