[TZInfo-announce] TZInfo v0.2.0 Released

[Philip Ross]

Version 0.2.0 of TZInfo has been released (based on version 2006c of the
underlying tz data).

GEM, zip and tar.gz files can be found at 
http://rubyforge.org/frs/?group_id=894. You can use 'gem update' to 
upgrade if you already have tzinfo installed.


Changes in this release:

* Timestamps are used rather than DateTime objects in zone files for 
times between 1970 and 2037 (the range of Time).

* Passed in Time objects are not converted to DateTime unless leaving 
the range of a Time.  This provides a substantial performance improvement).

* Integer timestamps (time in seconds since 1970-1-1) can now be used as 
well as Time and DateTime objects in all public methods that take times 
as parameters.

* A new tool has been committed to the TZInfo SVN repository to compare 
TZInfo conversions with output from zdump.

* The TZDataParser zone generation algorithm has been rewritten. It is 
now based on the zic code. TZInfo is now 100% compatible with zic/zdump 
output.

* The Riyadh Solar Time zones are now included again (the generation 
time has been reduced with the changes to TZDataParser).

* Binary mode is now used when writing zone and country files to get 
Unix (\n) new lines.

* Unnecessary quotes in zone identifier symbols are now omitted.

* The final transition to DST is now omitted in zone classes if there is 
a prior transition in the last year processed to standard time.

* The version of the tzdata has now been updated to 2006c 
(http://article.gmane.org/gmane.comp.time.tz/920).
