package timedesc-tzdb

Changelog

Timere-parse 0.0.7

• Added ISO week recognition rule with keyword iso-week

Timere 0.8.0

• Added ISO week pattern

  • iso_week_pattern, iso_years, iso_year_ranges, iso_weeks, iso_week_ranges

• Pattern resolver optimization

  • Added branch skipping for year, month, day, hour levels

  • This starts the search closer to the first actual potential match

• Fixed handling of length in deduce_child_result_space_bound_from_parent

  • Previously leads to incorrect result space computation, and may lead to time slots missing despite meeting criteria

Timedesc 0.9.1

• Moved to using hand rolled parser for tzdb and related parsing

  • Previous version using Angstrom causes stack overflow in JS targets

• Refreshed tzdb

Timedesc 0.9.0

• Moved sexp code into timedesc-sexp to further reduce core dependencies

• Replaced use of mparser with angstrom

Timedesc 0.8.0

• Significantly reduced number of dependencies, and moved JS, JSON code into separate packages

  • Removed dependencies: fmt, containers, oseq

  • Moved JSON code into timedesc-json package along with Yojson dependency

  • Moved tzlocal and tzdb stuff into their own separate packages (timedesc-tzlocal and timedesc-tzdb respectively)

  • Moved JS tzlocal backend into timedesc-tzlocal-js package

• Adjusted Time_zone.Db.Compressed API to remove use of Marshal

  • This in turn allows timedesc-tzdb.full to not depend on timedesc as the compressed copy is stable and can be stored in repo directly

Timedesc 0.7.0 (not released on OPAM)

• Added tzlocal.js backend for js_of_ocaml

• Added compressed binary encoding of time zone

  • Many thanks to @glennsl, see #46 for details

  • Replaced Time_zone.Db.Raw with Time_zone.Db.Compressed

  • Overall reduces tzdb storage usage by roughly 82%

• tzdb-full now only considers 1970 to 2040 to further cut down size

• Updated string conversion functions based on pretty printers which raise Date_time_cannot_deduce_offset_from_utc to raise the exception instead of returning None

  • This simplifies the handling as return type is now simply just string.

  • And for serious stuff users are expected to use only unambiguous date times anyway, which would not trigger this exception

• Added ISO8601 printing facilities to Timestamp module for consistency

  • They are just aliases to the RFC3339 printers
