Пакет php5-timezonedb: Информация

timezonedb PHP5 extension is a drop-in replacement for the builtin timezone database
that comes with PHP. You should only install this extension in case you need to get
a later version of the timezone database than the one that ships with PHP.

The data that this extension uses comes from the "Olson" database, which is
located at ftp://elsie.nci.nih.gov/pub/.
