impl FixedOffset
sourcepub fn east(secs: i32) -> FixedOffset
👎Deprecated since 0.4.23: use east_opt()
instead
pub fn east(secs: i32) -> FixedOffset
east_opt()
insteadMakes 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
.
sourcepub const fn east_opt(secs: i32) -> Option<FixedOffset>
pub const 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
.
§Example
use chrono::{FixedOffset, TimeZone};
let hour = 3600;
let datetime =
FixedOffset::east_opt(5 * hour).unwrap().with_ymd_and_hms(2016, 11, 08, 0, 0, 0).unwrap();

Trait Implementations§
source§impl<Tz: TimeZone> Add<FixedOffset> for DateTime<Tz>
impl<Tz: TimeZone> Add<FixedOffset> for DateTime<Tz>
Add FixedOffset
to the datetime value of DateTime
(offset remains unchanged).
§Panics
Panics if the resulting date would be out of range.
source§impl Add<FixedOffset> for NaiveDateTime
impl Add<FixedOffset> for NaiveDateTime
Add FixedOffset
to NaiveDateTime
.
