v0.3.1

• Remove colon from case statements to avoid warning in Ruby 1.8.5. #5198.
• Use temporary variable to avoid dynamic string warning from rdoc.
• Updated to tzdata version 2006j (https://mm.icann.org/pipermail/tz/2006-August/013767.html).

TZInfo v0.3.1 on RubyGems.org

v0.3.0

• New timezone data format. Timezone data now occupies less space on disk and takes less memory once loaded. #4142, #4144.
• Timezone data is defined in modules rather than classes. Timezone instances returned by Timezone.get are no longer instances of data classes, but are instead instances of new DataTimezone and LinkedTimezone classes.
• Timezone instances can now be used with Marshal.dump and Marshal.load. #4240.
• Added a Timezone.get_proxy method that returns a TimezoneProxy object for a given identifier.
• Country index data is now defined in a single module that is independent of the Country class implementation.
• Country instances can now be used with Marshal.dump and Marshal.load. #4240.
• Country has a new zone_info method that returns CountryTimezone objects containing additional information (latitude, longitude and a description) relating to each Timezone. #4140.
• Time zones within a Country are now returned in an order that makes geographic sense.
• The zdumptest utility now checks local to utc conversions in addition to utc to local conversions.
• eql? method defined on Country and Timezone that is equivalent to ==.
• == method of Timezone no longer raises an exception when passed an object with no identifier method.
• == method of Country no longer raises an exception when passed an object with no code method.
• hash method defined on Country that returns the hash of the code.
• hash method defined on Timezone that returns the hash of the identifier.
• Miscellaneous API documentation corrections and improvements.
• Timezone definition and indexes are now excluded from rdoc (the contents were previously ignored with #:nodoc: anyway).
• Removed no longer needed #:nodoc: directives from timezone data files (which are now excluded from the rdoc build).
• Installation of the gem now causes rdoc API documentation to be generated. #4905.
• When optimizing transitions to generate zone definitions, check the UTC and standard offsets separately rather than just the total offset to UTC. Fixes an incorrect abbreviation issue with Europe/London, Europe/Dublin and Pacific/Auckland.
• Eliminated unnecessary .nil? calls to give a minor performance gain.
• Timezone.all and Timezone.all_identifiers now return all the Timezone instances/identifiers rather than just those associated with countries. #4146.
• Added all_data_zones, all_data_zone_identifiers, all_linked_zones and all_linked_zone_identifiers class methods to Timezone.
• Added a strftime method to Timezone that converts a time in UTC to local time and then returns it formatted. %Z is replaced with the timezone abbreviation for the given time (for example, EST or EDT). #4143.
• Fix escaping of quotes in TZDataParser. This affected country names and descriptions of time zones within countries.

v0.2.2

• Use class-scoped instance variables to store the Timezone identifier and singleton instance. Loading a linked zone no longer causes the parent zone's identifier to be changed. The instance method of a linked zone class also now returns an instance of the linked zone class rather than the parent class. Closes #4502.
• The zdumptest utility now compares the TZInfo zone identifier with the zdump zone identifier.
• The zdumptestall utility now exits if not supplied with enough parameters.
• Updated to tzdata version 2006g (https://mm.icann.org/pipermail/tz/2006-May/013590.html).

TZInfo v0.2.2 on RubyGems.org

v0.2.1

• Fix a performance issue caused in 0.2.0 with Timezone.local_to_utc. Conversions performed on TimeOrDateTime instances passed to <=> are now cached as originally intended. Thanks to Michael Smedberg for spotting this.
• Fix a performance issue with the local_to_utc period search algorithm originally implemented in 0.1.0. The condition that was supposed to cause the search to terminate when enough periods had been found was only being evaluated in a small subset of cases. Thanks to Michael Smedberg and Jamis Buck for reporting this.
• Added abbreviation as an alias for TimezonePeriod.zone_identifier.
• Updated to tzdata version 2006d (https://mm.icann.org/pipermail/tz/2006-April/013517.html).
• Ignore any offset in DateTime instances passed in (as is already done for Time instances). All of the following now refer to the same UTC time (15:40 on 17 April 2006). Previously, the DateTime in the second line would have been interpreted as 20:40.

tz.utc_to_local(DateTime.new(2006, 4, 17, 15, 40, 0))  
tz.utc_to_local(DateTime.new(2006, 4, 17, 15, 40, 0).new_offset(Rational(5, 24)))  
tz.utc_to_local(Time.utc(2006, 4, 17, 15, 40, 0))  
tz.utc_to_local(Time.local(2006, 4, 17, 15, 40, 0))  

TZInfo v0.2.1 on RubyGems.org

v0.2.0

• Use timestamps rather than DateTime objects in zone files for times between 1970 and 2037 (the range of Time).
• Don't convert passed in Time objects to DateTime in most cases (provides a substantial performance improvement).
• Allow integer timestamps (time in seconds since 1970-1-1) to be used as well as Time and DateTime objects in all public methods that take times as parameters.
• Tool to compare TZInfo conversions with output from zdump.
• TZDataParser zone generation algorithm rewritten. Now based on the zic code. TZInfo is now 100% compatible with zic/zdump output.
• Riyadh Solar Time zones now included again (generation time has been reduced with TZDataParser changes).
• Use binary mode when writing zone and country files to get Unix (\n) new lines.
• Omit unnecessary quotes in zone identifier symbols.
• Omit the final transition to DST if there is a prior transition in the last year processed to standard time.
• Updated to tzdata version 2006c (https://mm.icann.org/pipermail/tz/2006-April/013500.html).

TZInfo v0.2.0 on RubyGems.org

v0.1.2

• Add lib directory to the load path when tzinfo is required. Makes it easier to use tzinfo gem when unpacked to vendor directory in rails.
• Updated to tzdata version 2006a (https://mm.icann.org/pipermail/tz/2006-January/013311.html).
• build_tz_classes rake task now handles running svn add and svn delete as new time zones and countries are added and old ones are removed.
• Return a better error when attempting to use a Timezone instance that was constructed with Timezone.new(nil). This will occur when using Rails' composed_of. When the timezone identifier in the database is null, attempting to use the Timezone will now result in an UnknownTimezone exception rather than a NameError.

TZInfo v0.1.2 on RubyGems.org

v0.1.1

• Time zones that are defined by a single unbounded period (e.g. UTC) now work again.
• Updated to tzdata version 2005q.
