otupy.types.data.datetime.DateTime

class DateTime(timestamp=None)

Bases: int

OpenC2 Date-Time

This is used to represents dates and times according to Sec. 3.4.2.2. According to OpenC2 specification, this is the time in milliseconds from the epoch.

Be careful that the timedate functions work with float timestamps expressed in seconds from the epoch, hence conversion is needed.

Methods

`as_integer_ratio`	Return integer ratio.
`bit_count`	Number of ones in the binary representation of the absolute value of self.
`bit_length`	Number of bits necessary to represent self in binary.
`conjugate`	Returns self, the complex conjugate of any int.
`from_bytes`	Return the integer represented by the given array of bytes.
`httpdate`	Format to HTTP headers
`to_bytes`	Return an array of bytes representing an integer.
`update`	Change Date-Time

Attributes

`denominator`	the denominator of a rational number in lowest terms
`imag`	the imaginary part of a complex number
`numerator`	the numerator of a rational number in lowest terms
`real`	the real part of a complex number

__add__(value, /): Return self+value.

__init__(timestamp=None)

Initialize Date-Time

The instance is initialized with the provided timestamp, or to the current time if no argument is given. The timestamp is expressed in milliseconds from the epoch, according to the Language Specification.

Parameters:: timestamp – The timestamp to initialize the instance.

__mul__(value, /): Return self*value.

as_integer_ratio()

Return integer ratio.

Return a pair of integers, whose ratio is exactly equal to the original int and with a positive denominator.

>>> (10).as_integer_ratio()
(10, 1)
>>> (-10).as_integer_ratio()
(-10, 1)
>>> (0).as_integer_ratio()
(0, 1)

bit_count()

Number of ones in the binary representation of the absolute value of self.

Also known as the population count.

>>> bin(13)
'0b1101'
>>> (13).bit_count()
3

bit_length()

Number of bits necessary to represent self in binary.

>>> bin(37)
'0b100101'
>>> (37).bit_length()
6

conjugate(): Returns self, the complex conjugate of any int.

denominator: the denominator of a rational number in lowest terms

classmethod from_bytes(bytes, byteorder='big', *, signed=False)

Return the integer represented by the given array of bytes.

bytes: Holds the array of bytes to convert. The argument must either support the buffer protocol or be an iterable object producing bytes. Bytes and bytearray are examples of built-in objects that support the buffer protocol.
byteorder: The byte order used to represent the integer. If byteorder is ‘big’, the most significant byte is at the beginning of the byte array. If byteorder is ‘little’, the most significant byte is at the end of the byte array. To request the native byte order of the host system, use `sys.byteorder’ as the byte order value. Default is to use ‘big’.
signed: Indicates whether two’s complement is used to represent the integer.

httpdate(timestamp=None)

Format to HTTP headers

Formats the timestamp according to the requirements of HTTP headers (RFC 7231). Use either the timestamp, if provided, or the current time. :param timestamp: The timestamp to format, expressed in milliseconds from the epoch. :return RFC 7231 representation of the timestamp.

imag: the imaginary part of a complex number

numerator: the numerator of a rational number in lowest terms

real: the real part of a complex number

to_bytes(length=1, byteorder='big', *, signed=False)

Return an array of bytes representing an integer.

length: Length of bytes object to use. An OverflowError is raised if the integer is not representable with the given number of bytes. Default is length 1.
byteorder: The byte order used to represent the integer. If byteorder is ‘big’, the most significant byte is at the beginning of the byte array. If byteorder is ‘little’, the most significant byte is at the end of the byte array. To request the native byte order of the host system, use `sys.byteorder’ as the byte order value. Default is to use ‘big’.
signed: Determines whether two’s complement is used to represent the integer. If signed is False and a negative integer is given, an OverflowError is raised.

update(timestamp=None)

Change Date-Time

Change the timestamp beard by the instance. The timestamp is expressed in milliseconds from the epoch. If no timestamp is given, sets to the current time.

Parameters:: timestamp – The timestamp to initialize the instance.
