-Behind the scenes, rufus-scheduler uses [tzinfo](http://tzinfo.github.io/) to deal with timezones.
-
-Here is a [list of timezones](misc/tz_all.txt) known to my Debian GNU/Linux 7. It was generated with this script:
-
-```ruby
-require 'tzinfo'
-TZInfo::Timezone.all.each { |tz| puts tz.name }
-```
-
-Unknown timezones, typos, will be rejected by tzinfo thus rufus-scheduler.
-
-On its own tzinfo derives the timezones from the system's information. On some system it needs some help, one can install the 'tzinfo-data' gem to provide the missing information.
