dfDateTime
dfDateTime is a Python 3 library for digital forensics that provides date and time objects to preserve accuracy and precision. It is designed for handling timestamps in forensic investigations.
Description
dfDateTime, or Digital Forensics date and time, is a specialized library for Python 3 used in digital forensics to manage date and time data accurately. It offers date and time objects that maintain precision, which is critical in forensic analysis where timestamp integrity can affect case outcomes.
Use cases include processing file system timestamps, log files, and other time-sensitive artifacts from disk images or memory dumps. Investigators rely on it to avoid precision loss common in standard Python datetime handling.
The library is part of the Kali Linux forensics toolkit, installed via the python3-dfdatetime package, with a small footprint of 245 KB. It depends only on python3, making it lightweight for forensic workflows.
How It Works
dfDateTime provides custom date and time objects tailored for digital forensics, preserving the full accuracy and precision of timestamps from forensic sources like file systems or network captures. Unlike standard Python datetime, it handles specialized formats and avoids rounding errors or precision loss during conversions and calculations.
Installation
sudo apt install python3-dfdatetimeExamples
import dfdatetimedt = dfdatetime.DFDateTime()print(dt.parse_string('2023-01-01 12:00:00'))dfdatetime.time_elements_from_seconds(seconds)dfdatetime.date_elements_to_string(date_elements)dt = dfdatetime.DFDateTime.from_filetime(132123456789)
