Version history

User-visible changes from 1.0.0-beta1 onwards. See the project repository for more details.

1.0.2, not yet released

Bug fixes:

  • Fixed issue 174 which made the "Asia/Amman" time zone (Jordan) give incorrect values or a NullReferenceException when asked for a value in 2040 (and possibly other times). Other time zones should not be affected.

1.0.1, released 2012-11-13 with tzdb 2012i

No API changes; this release was purely to fix a problem with the NodaTime.Testing package.

1.0.0, released 2012-11-07 with tzdb 2012i

API changes:

  • Added the CalendarSystem.Id property that returns a unique ID for a calendar system, along with the ForId() factory method and Ids static property; ToString() now returns the calendar ID rather than the name
  • Added support for the c custom format specifier for local date values, which includes the calendar ID, representing the calendar system
  • Added support for the ; custom format specifier to parse both comma and period for fractions of a second; InstantPattern.ExtendedIsoPattern, LocalTimePattern.ExtendedIsoPattern, and LocalDateTimePattern.ExtendedIsoPattern now accept both as separators (issues [140]issue 140 and [141]issue 141)
  • Added support for the r standard pattern for LocalDateTime that includes the calendar system
  • Renamed the CreateWithInvariantInfo() method on the pattern types to CreateWithInvariantCulture() (issue 137)

Other:

  • Set specific files to be ignored in ZoneInfoCompiler, so we don't need to remove them manually each time

1.0.0-rc1, released 2012-11-01 with tzdb 2012h

API changes:

  • Renamed DateTimeZone.GetOffsetFromUtc() to DateTimeZone.GetUtcOffset() to match the BCL (issue 121)
  • Added LocalDate.FromWeekYearWeekAndDay() (issue 120)
  • Text formats can now parse negative values for absolute years (issue 118)
  • Tick, SecondOfDay and MillisecondOfDay properties removed from time-based types (issue 103)
  • Removed the NodaCultureInfo and NodaFormatInfo types (issue 131 and related issues), removed the FormatInfo property and WithFormatInfo() method on pattern types, and changed the culture-specific pattern factory methods to take a CultureInfo rather than a NodaFormatInfo
  • Removed EmptyDateTimeZoneSource
  • Many classes are now sealed: PeriodPattern, BclDateTimeZoneProvider, BclDateTimeZoneSource, DateTimeZoneCache, and ZoneInterval, along with various exception types and NodaTime.Testing.SingleTransitionDateTimeZone
  • The names of the special resources used by TzdbDateTimeZoneSource (VersionKey, etc) are now internal
  • Format of the special resource keys has changed; clients using custom-built TZDB resources will need to rebuild

Bug fixes:

  • Various fixes to BclDateTimeZone not working the same way as a BCL TimeZoneInfo (issues [114]issue 114, [115]issue 115, and [122]issue 122)

Other:

  • Noda Time assemblies are now signed (issue 35)
  • Removed support for building under Visual Studio 2008 (issue 107)

1.0.0-beta2, released 2012-08-04 with tzdb 2012e

API changes:

  • Overhaul of how to get a DateTimeZone from an ID:

    • IDateTimeZoneProvider (SPI for time zones) renamed to IDateTimeZoneSource, along with similar renaming for the built-in sources
    • New interface IDateTimeZoneProvider aimed at callers, with caching assumed
    • New class DateTimeZoneProviders with static properties to access the built-in providers: TZDB, BCL and default (currently TZDB)
    • Removed various DateTimeZone static methods in favour of always going via an IDateTimeZoneProvider implementation
    • DateTimeZoneCache now public and implements IDateTimeZoneProvider
  • DateTimeZone no longer has internal abstract methods, making third-party implementations possible (issue 77)

  • DateTimeZone now implements IEquatable<DateTimeZone>, and documents what it means for time zones to be equal (issue 81)

  • New core type: OffsetDateTime representing a local date/time and an offset from UTC, but not full time zone information

  • Added a new standard offset pattern of G, which is like g but using "Z" for zero; also available as OffsetPattern.GeneralInvariantPatternWithZ

  • Period and PeriodBuilder no longer differentiate between absent and zero components (to the extent that they did at all): Units has been removed from Period, period formatting now omits all zero values unconditionally, and the Year (etc) properties on PeriodBuilder are no longer nullable (issue 90)

  • Removed the BCL parsing methods and some of the BCL formatting methods from Instant, LocalDate, LocalDateTime, and Offset in favour of the pattern-based API (issue 87)

  • Duration.ToString() and Interval.ToString() now return more descriptive text

  • Removed DateTimeZone.GetSystemDefaultOrNull(); callers should use the provider's GetSystemDefault() method and (if necessary) catch the TimeZoneNotFoundException that it can throw (issue 61)

  • Removed DateTimeZone.UtcId and DateTimeZone.IsFixed (issues [64]issue 64 and [62]issue 62)

  • Removed most of the convenience static properties on Duration (e.g. Duration.OneStandardDay) in favour of the existing static methods; removed MinValue and MaxValue, and added Epsilon (issue 70)

  • Removed Instant.BeginningOfTimeLabel and Instant.EndOfTimeLabel

  • Instant.InIsoUtc renamed to InUtc

  • Instant.UnixEpoch moved to NodaConstants.UnixEpoch; NodaConstants.DateTimeEpochTicks replaced by BclEpoch

  • Added Instant.PlusTicks()

  • LocalDate.LocalDateTime property changed to LocalDate.AtMidnight() method (issue 56)

  • LocalTime now implements IComparable<LocalTime> (issue 51)

  • Added a LocalTime constructor taking hours and minutes (issue 53)

  • Removed "component" properties from Offset, and renamed the "total" properties to just Ticks and Milliseconds

  • Removed Offset.Create() methods (and moved them in slightly different form in a new internal TestObjects class in NodaTime.Test)

  • Added Period.ToDuration() (issue 55) and Period.CreateComparer() (issue 69)

  • Period.Empty renamed to Period.Zero (as part of issue 90)

  • PeriodBuilder no longer implements IEquatable<PeriodBuilder> (issue 91)

  • Removed SystemClock.SystemNow in favour of using SystemClock.Instance.Now if you really have to

  • Added ZonedDateTime.ToOffsetDateTime(), which returns the OffsetDateTime equivalent to a ZonedDateTime

  • Removed the Buddhist Era (as there is no Buddhist calendar implementation)

  • NodaTime.Testing.StubClock renamed to FakeClock, and gains an auto-advance option (issues [72]issue 72 and [73]issue 73)

  • NodaTime.Testing.TimeZones.SingleTransitionZone renamed to SingleTransitionDateTimeZone

Bug fixes:

  • Many
