[Haskell-cafe] ANN: timezone-olson V0.1.4

[Yitzchak Gale]

Version 0.1.4 of timezone-olson has been released on Hackage.
This version adds support for version 3 olson timezone files,
which are now beginning to appear in the wild.
Thanks to Renzo Carbonara and Oliver Charles for providing
this update.

The timezone-olson package provides a parser and renderer
for binary Olson timezone files whose format is specified by
the tzfile(5) man page on Unix-like systems. For more
information about this format, see:

http://www.twinsun.com/tz/tz-link.htm

Functions are provided for converting the parsed data into
'TimeZoneSeries' objects from the timezone-series package [1].
On many platforms, binary Olson timezone files suitable for use
with this package are available in the directory

/usr/share/zoneinfo

and its subdirectories on your computer.

Home page: http://projects.haskell.org/time-ng/

Note that support for tzfile versions 2 and 3 is not complete. We
parse all of the explicit clock transitions, but we do not yet
support the textual POSIX-style time zone specifications
that can be included; currently, those only affect clock transitions
that are predicted to occur far in the future. We also do not yet support
parsing the leap second tables that are now provided in olson files;
see the function Data.Time.Clock.TAI.parseTAIUTCDATFile in
Ashely Yakeley's time library [2] for an alternative.
