Struct chrono_simpletz::TimeZoneZst

pub struct TimeZoneZst<const HOUR: i32, const MINUTE: u32>;

Represent Fixed Timezone with zero sized type and const generics. HOUR and MINUTE must be in valid range(-23 <= HOUR <= 23 & MINUTE < 60), otherwise compile error will occur.

let tz = TimeZoneZst::<26, 0>::new();

Implementations

impl<const HOUR: i32, const MINUTE: u32> TimeZoneZst<HOUR, MINUTE>

pub const OFFSET_SECS: i32 = _

Gets the offset seconds. Should use FIXED_OFFSET instead of using this directory.

pub const IS_IN_VALID_RANGE: bool = _

Checks whether the HOUR and MINUTE is in valid range(-23 <= HOUR <= 23 & MINUTE < 60). This does not check whether the timezone is known.

pub const FIXED_OFFSET: FixedOffset = _

Gets the FixedOffset without creating a instance.

pub const fn new() -> Self

Creates new TimeZoneZst

pub fn today() -> Date<Self>

👎Deprecated since 0.3.0

Returns a Date which corresponds to the current date. Only available with clock feature.

pub fn now() -> DateTime<Self>

Returns a DateTime which corresponds to the current date. Only available with clock feature.
