Struct chrono::offset::FixedOffset

[+] Show declaration

pub struct FixedOffset { /* fields omitted */ }

[−] Expand description

The time zone with fixed offset, from UTC-23:59:59 to UTC+23:59:59.

Using the TimeZone methods on a FixedOffset struct is the preferred way to construct DateTime<FixedOffset> instances. See the east and west methods for examples.

Implementations

impl FixedOffset[−]

pub fn east(secs: i32) -> FixedOffset[−]

Makes a new FixedOffset for the Eastern Hemisphere with given timezone difference. The negative secs means the Western Hemisphere.

Panics on the out-of-bound secs.

Example

use chrono::{FixedOffset, TimeZone};
let hour = 3600;
let datetime = FixedOffset::east(5 * hour).ymd(2016, 11, 08)
                                          .and_hms(0, 0, 0);
assert_eq!(&datetime.to_rfc3339(), "2016-11-08T00:00:00+05:00")

pub fn east_opt(secs: i32) -> Option<FixedOffset>[−]

Makes a new FixedOffset for the Eastern Hemisphere with given timezone difference. The negative secs means the Western Hemisphere.

Returns None on the out-of-bound secs.

pub fn west(secs: i32) -> FixedOffset[−]

Makes a new FixedOffset for the Western Hemisphere with given timezone difference. The negative secs means the Eastern Hemisphere.

Example
