Not sure what happened, this page/code always worked before, no changes were made to the code, only the box was powered down, moved and powered back up, the code seems to still be doing its job but spewing out these errors right on the page.

Again no changes were made.

Warning: strtotime() [function.strtotime]: It is not safe to rely on the system's timezone settings. Please use the date.timezone setting, the TZ environment variable or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier.

I think it is complaining about the lack of a tzfile - on Linux: /etc/timezone (should be a one liner that names a timezone database file) . Try the zdump command which should read the tzfile- if that shows nothing, then try the tzselect command (read the info page first).
