This library's functions are used to retrieve time changes and date/time characteristics for a given TZ. Based on data provided by system timezone files and low-level parsing library. System TZfiles default location can be overriden with the TZFILES_DIR environment variable.
There are two functions, one using the other's result:
get_timechanges obtains time changes for specified year, or all time changes recorded in the TZfile if no year is specified.
get_zoneinfo further parses the data to provide useful and human-readable output.
Example with get_zoneinfo: ```rust extern crate tzparse;
fn main() { match tzparse::gettimechanges("Europe/Paris", Some(2019)) { Some(tz) => println!("{:?}", tzparse::getzoneinfo(&tz).unwrap()), None => println!("Timezone not found") }; } ```
Outputs:
{ utc_datetime: 2019-09-27T07:04:09.366157Z, datetime: 2019-09-27T09:04:09.366157+02:00,
dst_from: Some(2019-03-31T01:00:00Z), dst_until: Some(2019-10-27T01:00:00Z),
raw_offset: 3600, dst_offset: 7200, utc_offset: +02:00, abbreviation: "CEST" }
The get_timechanges used alone ouputs:
[Timechange { time: 2019-03-31T01:00:00Z, gmtoff: 7200, isdst: true, abbreviation: "CEST" },
Timechange { time: 2019-10-27T01:00:00Z, gmtoff: 3600, isdst: false, abbreviation: "CET" }]
