[dependabot]

Bumps chrono from 0.4.26 to 0.4.31.

Release notes

Sourced from chrono's releases.

0.4.31

Another maintenance release. It was not a planned effort to improve our support for UNIX timestamps, yet most PRs seem related to this.

Deprecations

• Deprecate timestamp_nanos in favor of the non-panicking timestamp_nanos_opt (#1275)

Additions

• Add DateTime::<Utc>::from_timestamp (#1279, thanks @​demurgos)
• Add TimeZone::timestamp_micros (#1285, thanks @​emikitas)
• Add DateTime<Tz>::timestamp_nanos_opt and NaiveDateTime::timestamp_nanos_opt (#1275)
• Add UNIX_EPOCH constants (#1291)

Fixes

• Format day of month in RFC 2822 without padding (#1272)
• Don't allow strange leap seconds which are not on a minute boundary initialization methods (#1283) This makes many methods a little more strict:
  • NaiveTime::from_hms_milli
  • NaiveTime::from_hms_milli_opt
  • NaiveTime::from_hms_micro
  • NaiveTime::from_hms_micro_opt
  • NaiveTime::from_hms_nano
  • NaiveTime::from_hms_nano_opt
  • NaiveTime::from_num_seconds_from_midnight
  • NaiveTime::from_num_seconds_from_midnight_opt
  • NaiveDate::and_hms_milli
  • NaiveDate::and_hms_milli_opt
  • NaiveDate::and_hms_micro
  • NaiveDate::and_hms_micro_opt
  • NaiveDate::and_hms_nano
  • NaiveDate::and_hms_nano_opt
  • NaiveDateTime::from_timestamp
  • NaiveDateTime::from_timestamp_opt
  • TimeZone::timestamp
  • TimeZone::timestamp_opt
• Fix underflow in NaiveDateTime::timestamp_nanos_opt (#1294, thanks @​crepererum)

Documentation

• Add more documentation about the RFC 2822 obsolete date format (#1267)

Internal

• Remove internal __doctest feature and doc_comment dependency (#1276)
• CI: Bump actions/checkout from 3 to 4 (#1280)
• Optimize NaiveDate::add_days for small values (#1214)
• Upgrade pure-rust-locales to 0.7.0 (#1288, thanks @​jeremija wo did good improvements on pure-rust-locales)

Thanks to all contributors on behalf of the chrono team, @​djc and @​pitdicker!

0.4.30

In this release, we have decided to swap out the chrono::Duration type (which has been a re-export of time 0.1 Duration type) with our own definition, which exposes a strict superset of the time::Duration API. This helps avoid warnings about the [CVE-2020-26235] and [RUSTSEC-2020-0071] advisories for downstream users and allows us to improve the Duration API going forward.
