Struct DateTime 

pub struct DateTime { /* private fields */ }

Representation of a moment in time.

Zip files use an old format from DOS to store timestamps, with its own set of peculiarities. For example, it has a resolution of 2 seconds!

A DateTime can be stored directly in a zipfile with [FileOptions::last_modified_time], or read from one with [ZipFile::last_modified]

Warning

Because there is no timezone associated with the DateTime, they should ideally only be used for user-facing descriptions. This also means DateTime::to_time returns an OffsetDateTime (which is the equivalent of chrono’s NaiveDateTime).

Modern zip files store more precise timestamps, which are ignored by crate::read::ZipArchive, so keep in mind that these timestamps are unreliable. We’re working on this.

Implementations

impl DateTime

pub fn from_msdos(datepart: u16, timepart: u16) -> DateTime

Converts an msdos (u16, u16) pair to a DateTime object

pub fn from_date_and_time( year: u16, month: u8, day: u8, hour: u8, minute: u8, second: u8, ) -> Result<DateTime, ()>

Constructs a DateTime from a specific date and time

The bounds are:

• year: [1980, 2107]
• month: [1, 12]
• day: [1, 31]
• hour: [0, 23]
• minute: [0, 59]
• second: [0, 60]

pub fn from_time(dt: OffsetDateTime) -> Result<DateTime, ()>

👎Deprecated: use DateTime::try_from()

Converts a OffsetDateTime object to a DateTime

Returns Err when this object is out of bounds

pub fn timepart(&self) -> u16

Gets the time portion of this datetime in the msdos representation

pub fn datepart(&self) -> u16

Gets the date portion of this datetime in the msdos representation

pub fn to_time(&self) -> Result<OffsetDateTime, ComponentRange>

Converts the DateTime to a OffsetDateTime structure

pub fn year(&self) -> u16

Get the year. There is no epoch, i.e. 2018 will be returned as 2018.

pub fn month(&self) -> u8

Get the month, where 1 = january and 12 = december

Warning

When read from a zip file, this may not be a reasonable value

pub fn day(&self) -> u8

Get the day

Warning

When read from a zip file, this may not be a reasonable value

pub fn hour(&self) -> u8

Get the hour

Warning

When read from a zip file, this may not be a reasonable value

pub fn minute(&self) -> u8

Get the minute

Warning

When read from a zip file, this may not be a reasonable value

pub fn second(&self) -> u8

Get the second

Warning

When read from a zip file, this may not be a reasonable value
