v0.4.38
This release bring a ca. 20% improvement to the performance of the formatting code, and a convenient days_since
method for the Weekday
type.
Chrono 0.4.38 also removes the long deprecated rustc-serialize
feature. Support for rustc-serialize
will be soft-destabilized in the next Rust edition. Removing the feature will not break existing users of the feature; Cargo will just not update dependents that rely on it to newer versions of chrono.
In chrono 0.4.36 we made an accidental breaking change by switching to derive(Copy)
for DateTime
instead of a manual implementation. It is reverted in this release.
Removals
- Remove
rustc-serialize
feature (#1548, thanks @workingjubilee)
Additions
- Add
Weekday::days_since
(#1249, based on #216 by @clarfonthey) - Add

andTimeDelta::checked_div
(#1565, thanks @Zomtir)
Fixes
- Return error when rounding with a zero duration (#1474, thanks @Dav1dde)
- Manually implement

(#1573)

- Inline

v.0.4.8
v0.4.37
Version 0.4.36 introduced an unexpected breaking change and was yanked. In it LocalResult
was renamed to MappedLocalTime
to avoid the impression that it is a Result
type were some of the results are errors. For backwards compatibility a type alias with the old name was added.
As it turns out there is one case where a type alias behaves differently from the regular enum: you can't import enum variants from a type alias with use chrono::LocalResult::*
. With 0.4.37 we make the new name MappedLocalTime
the alias, but keep using it in function signatures and the documentation as much as possible.
See also the release notes of chrono 0.4.36 from yesterday for the yanked release.
v0.4.36
This release un-deprecates the methods on TimeDelta
that were deprecated with the 0.4.35 release because of the churn they are causing for the ecosystem.
New is the DateTime::with_time()
method. As an example of when it is useful:
use chrono::{Local, NaiveTime};
// Today at 12:00:00
let today_noon = Local::now().with_time(NaiveTime::from_hms_opt(12, 0, 0).unwrap());
Additions
- Add
DateTime::with_time()
(#1510)
Deprecations
- Revert
TimeDelta
deprecations (#1543) - Deprecate
TimeStamp::timestamp_subsec_nanos
, which was missed in the 0.4.35 release (#1486)
Documentation
- Correct version number of deprecation notices (#1486)
- Fix some typos (#1505)
- Slightly improve serde documentation (#1519)
- Main documentation: simplify links and reflow text (#1535)
Internal
- CI: Lint benchmarks (#1489)
- Remove unnessary
Copy
andSend
impls (#1492, thanks @erickt) - Backport streamlined
NaiveDate
unit tests (#1500, thanks @Zomtir) - Rename
LocalResult

, add alias (#1501) - Update windows-bindgen to 0.55 (#1504)
- Avoid duplicate imports, which generate warnings on nightly (#1507)
- Add extra debug assertions to
NaiveDate::from_yof
(#1518) - Some small simplifications to
DateTime::date_naive
andNaiveDate::diff_months
(#1530) - Remove
unwrap

type (#1533) - Use different method to ignore feature-dependent doctests (#1534)

v0.4.35
Most of our efforts have shifted to improving the API for a 0.5 release, for which cleanups and refactorings are landing on the 0.4.x branch.
The most significant changes in this release are two sets of deprecations.
-
We deprecated all timestamp-related methods on
NaiveDateTime
. The reason is that a timestamp is defined to be in UTC. TheNaiveDateTime
type doesn't know the offset from UTC, so it was technically wrong to have these methods. The alternative is to use the similar methods on theDateTime<Utc>
type, or from theTimeZone
trait.Converting from
NaiveDateTime
toDateTime<Utc>
is simple with.and_utc()
, and in the other direction with.naive_utc()
. -
The panicking constructors of
TimeDelta
(the new name of theDuration
type) are deprecated. This was the last part of chrono that defaulted to panicking on error, dating from before rust 1.0. -
A nice change is that
NaiveDate
now includes a niche. So nowOption<NaiveDate>
,Option<NaiveDateTime>
andOption<DateTime<Tz>>
are the same size as their base types. -
format::Numeric
andformat::Fixed
are marked asnon_exhaustive
. This will allow us to improve our formatting and parsing support, and we have reason to believe this breaking change will have little to no impact on users.

v0.4.34
Notable changes
- In chrono 0.4.34 we finished the work to make all methods const where doing so is supported by rust 1.61.
- We renamed the
Duration
type toTimeDelta
. This removes the confusion between chrono's type and the laterDuration
type in the standard library. It will remain available under the old name as a type alias for compatibility. - The Windows implementation of
Local
is rewritten. The new version avoids panics when the date is outside of the range supported by windows (the years 1601 to 30828), and gives more accurate results during DST transitions. - The
Display
format ofTimeDelta
is modified to conform better to ISO 8601. Previously it converted all values greater than 24 hours to a value with days. This is not correct, as doing so changes the duration from an 'accurate' to a 'nominal' representation to use ISO 8601 terms.
Fixes
- Add missing range check in
TimeDelta::milliseconds
(#1385, thanks @danwilliams) - Remove check for
DurationExceedsTimestamp
inDurationRound
(#1403, thanks @joroKr21) - Fix localized formatting with

GetTimeZoneInformationForYear
(#1017)
Additions

TimeDelta::try_milliseconds
(#1385, thanks @danwilliams) - Add
TimeDelta::new
(#1337) - Add
StrftimeItems::{parse, parse_to_owned}
and more documentation (#1184) - More standard traits and documentation for
format::Locale
(via chronotope/pure-rust-locales#8)
Changes
- Rename
Duration
toTimeDelta
, add type alias (#1406) - Make
TimeDelta
methods const (#1337) - Make remaining methods of
NaiveDate
,NaiveWeek
,NaiveTime
andNaiveDateTime
const where possible (#1337) - Make methods on
DateTime
const where possible (#1400) - Make
