Build unison 2.40.65 (ocaml 4.0) to work between Ubuntu 12.04 and OS X Mountain Lion

I could not find any pre-built binaries (macports) that worked properly out of the box between my laptop and the ubuntu server. So build your own.

NOTE: This will break unison with hosts that use unison 2.40.65 built with ocaml 3.x!


Fix PHP 5.3 timezone warnings for drupal

I recently installed drupal 6.14 on Snow Leopard and got these timezone warnings.

warning: strtotime() [function.strtotime]: It is not safe to rely on the system's timezone settings. 
You are *required* to use the date.timezone setting 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. 
We selected 'Asia/Tokyo' for 'JST/9.0/no DST' instead in /Users/<user>/Sites/drupal/sites/all/modules/views/modules/node/views_handler_argument_dates_various.inc on line 67.
