TZInfo - Ruby Time Zone Library

Gem Version Travis CI Build Status AppVeyor Build Status

TZInfo is a Ruby library that provides access to time zone data and allows times to be converted using time zone rules.

Data Sources

TZInfo requires a source of timezone data. There are two options:

  1. A zoneinfo directory containing timezone definition files. These files are generated from the IANA Time Zone Database using the zic utility. Most Unix-like systems include a zoneinfo directory.
  2. The TZInfo::Data library (the tzinfo-data gem). TZInfo::Data contains a set of Ruby modules that are also generated from the IANA Time Zone Database.

By default, TZInfo will attempt to use TZInfo::Data. If TZInfo::Data is not available, then TZInfo will search for a zoneinfo directory instead.

Custom data sources can also be created and used with TZInfo.
