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

• Fixed handling of negative month day

  • Bug introduced in 84792815ccfa1f8ae4bd9c228e314491dc31456a during reintroduction of pattern resolver branch skipping optimization
  • The commit was made after relese of Timere 0.7.0, so the bug only affected users who were pinning the repo directly

Timedesc 2.0.0

• Renamed Zoneless.make to Zoneless.of_date_and_time for consistency

• Adjusted Time_zone_info API

  • Renamed fixed_offset_from_utc to offset_from_utc for consistency

• Fixed tzdb compression/decompression code

  • See issue 74
• Renamed local_result to local_dt_result

Timedesc 1.2.0

• Added functions to reduce friction during construction of date time

  • of_date_and_time
  • of_date_and_time_exn
  • of_date_and_time_unambiguous

  • to_string
  • pp

Timedesc 1.1.0

• Exposed the following functions in Utils

  • iso_week_date_of_jd
  • jd_of_iso_week_date

• Made ISO_week.make slightly more lenient in the year range accepted

  • Changing range from [0, 9999] to [-1, 10000]
  • Previously, Timedesc.iso_week would sometimes fail in the edge cases year 0 and 9999

Timedesc 1.0.0

• Fixed get_local_tz_for_arg error message
• Refreshed tzdb

• Added RFC9110 (HTTP Semantics) printers

  • pp_rfc9110
  • to_rfc9110
  • Timestamp.pp_rfc9110
  • Timestamp.to_rfc9110
  • Date.pp_rfc9110

• and parsers

  • of_rfc9110
  • of_rfc9110_exn
  • Timestamp.of_rfc9110
  • Timestamp.of_rfc9110_exn

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
