Microsoft Windows SYSTEMTIME structure: Python parsing library

Microsoft Windows SYSTEMTIME structure, stores individual components of date and time as individual fields, up to millisecond precision.

This page hosts a formal specification of Microsoft Windows SYSTEMTIME structure using Kaitai Struct. This specification can be automatically translated into a variety of programming languages to get a parsing library.

Usage

Parse a local file and get structure in memory:

data = WindowsSystemtime.from_file("path/to/local/file.Microsoft Windows SYSTEMTIME structure")

Or parse structure from a bytes:

from kaitaistruct import KaitaiStream, BytesIO

raw = b"\x00\x01\x02..."
data = WindowsSystemtime(KaitaiStream(BytesIO(raw)))

After that, one can get various attributes from the structure by invoking getter methods like:

data.year # => Year
