Struct LocalTimeOffsetEntry 

pub struct LocalTimeOffsetEntry {
    pub country_code: LangCode,
    pub country_region_id: u8,
    pub local_time_offset_negative: bool,
    pub local_time_offset_bcd: u16,
    pub next_time_offset_bcd: u16,
    /* private fields */
}

One per-country offset entry.

Fields

country_code: LangCode

ISO 3166 alpha country code.

country_region_id: u8

6-bit country_region_id for sub-national regions.

local_time_offset_negative: bool

Polarity: false = offset is positive (local = UTC + offset), true = offset is negative (local = UTC − offset).

local_time_offset_bcd: u16

16-bit BCD HHMM local time offset.

next_time_offset_bcd: u16

16-bit BCD HHMM next offset (applied after time_of_change).

Implementations

impl LocalTimeOffsetEntry

pub fn new( country_code: LangCode, country_region_id: u8, local_time_offset_negative: bool, local_time_offset_bcd: u16, time_of_change_raw: [u8; 5], next_time_offset_bcd: u16, ) -> Self

Create a new entry with all fields specified.

pub fn time_of_change_parts(&self) -> (u16, Option<u8>, Option<u8>, Option<u8>)

Decode time_of_change_raw into its MJD + BCD HHMMSS components without requiring the chrono feature.

Returns (mjd, hours, minutes, seconds). Each BCD field is None if its nibbles are non-decimal.

pub fn time_of_change_raw(&self) -> [u8; 5]

The raw 5-byte MJD+BCD time-of-change field (for serialization).

pub fn set_time_of_change_raw(&mut self, raw: [u8; 5])

Set the time_of_change_raw field directly.

impl LocalTimeOffsetEntry

pub fn local_time_offset(&self) -> Option<Duration>

Available on crate feature chrono only.

Decode local_time_offset (BCD HHMM, signed by local_time_offset_negative) to a chrono::Duration. None if the BCD nibbles are out of range.

pub fn next_time_offset(&self) -> Option<Duration>

Available on crate feature chrono only.

Decode next_time_offset (BCD HHMM) to a chrono::Duration. It shares the single local_time_offset_negative polarity bit (EN 300 468 §6.2.20). None if the BCD nibbles are out of range.

pub fn time_of_change(&self) -> Option<DateTime<Utc>>

Available on crate feature chrono only.

Decode time_of_change_raw (16-bit MJD + 24-bit BCD UTC) to a UTC datetime. None if the date/time fields are out of range.

pub fn set_time_of_change(&mut self, dt: DateTime<Utc>) -> Result<()>

Available on crate feature chrono only.

Set the time_of_change, encoding it into the 40-bit raw field.

Errors

ValueOutOfRange if the date is outside the representable 16-bit MJD range.

pub fn set_offsets(&mut self, local: Duration, next: Duration) -> Result<()>

Available on crate feature chrono only.

Set both offsets and the shared polarity bit from signed durations.

The wire format carries one polarity bit for both offsets, so local and next must share a sign (zero matches either).

Errors

ValueOutOfRange if the two offsets disagree in sign or a magnitude is 100 hours or longer.
