10+
11+ ###Added
12+
13+ - ` Time::MAX ` , equivalent to` time!(23:59:59.999999999) `
14+ - ` [year repr:century] ` is now supported in format descriptions. When used in conjunction with
15+ ` [year repr:last_two] ` , there is sufficient information to parse a date. Note that with the
16+ ` large-date ` feature enabled, there is an ambiguity when parsing the two back-to-back.
17+ - Parsing of` strftime ` -style format descriptions, located at
18+ ` time::format_description::parse_strftime_borrowed ` and
19+ ` time::format_description::parse_strftime_owned `
20+ - ` time::util::refresh_tz ` and` time::util::refresh_tz_unchecked ` , which updates information
21+ obtained via the` TZ ` environment variable. This is equivalent to the` tzset ` syscall on Unix-like
22+ systems, with and without built-in soundness checks, respectively.
23+
24+ ###Changed
25+
26+ - Obtaining the system UTC offset on Unix-like systems should now succeed when multi-threaded.
27+ However, if the` TZ ` environment variable is altered, the program will not be aware of this until
28+ ` time::util::refresh_tz ` or` time::util::refresh_tz_unchecked ` is called.` refresh_tz ` has the
29+ same soundness requirements as obtaining the system UTC offset previously did, with the
30+ requirements still being automatically enforced.` refresh_tz_unchecked ` does not enforce these
31+ requirements at the expense of being` unsafe ` . Most programs should not need to call either
32+ function.
33+
34+ Due to this change, the` time::util::local_offset ` module has been deprecated in its entirety. The
35+ ` get_soundness ` and` set_soundness ` functions are now no-ops.
36+
37+ Note that while calls_ should_ succeed, success is not guaranteed in any situation. Downstream
38+ users should always be prepared to handle the error case.
39+
40+ ###Fixed
41+
42+ - Floating point values are truncated, not rounded, when formatting.
43+ - RFC3339 allows arbitrary separators between the date and time components.
44+ - Serialization of negative` Duration ` s less than one second is now correct. It previously omitted
45+ the negative sign.
46+ - ` From<js_sys::Date> for OffsetDateTime ` now ensures sub-millisecond values are not erroneously
47+ returned.
