Timere 0.9.0

  • Added ISO week pattern

    • iso_week_pattern, iso_years, iso_year_ranges, iso_weeks, iso_week_ranges

  • Changed error messages to not be capitalized

Timedesc 3.1.1

  • Refreshed tzdb

Timedesc 3.1.0

  • Fixed 12hour handling in pretty-printer

  • Added am/pm to format string

  • Replaced pretty print with pretty-print to be consistent with upstream stdlib Format, and fmt package documentation

  • Changed error messages to not be capitalized

  • Added timedesc-tzlocal.unix-or-utc and made it the default backend

  • Updated documentation of Time_zone_info

  • Replaced local_dt_result with local_date_time_result for consistency

  • Changed signature of equal_local_date_time_result so the argument for the inner equality check function is no longer labelled

Timere 0.8.0

  • 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

    • 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

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
