Worked on the pandas-stubs repository to enhance DateTime Utilities by enabling the to_offset function to accept datetime.timedelta inputs, aligning stub behavior more closely with core pandas and improving support for duration-based offsets. This update addressed static typing needs and streamlined IDE integration for downstream users. The work involved targeted code formatting and organization, utilizing Python and tools like isort and black to improve readability and maintainability across the codebase. Emphasis was placed on clean import management and consistent style, reflecting a focus on both functional enhancement and code quality. No bugs were fixed during this period, with efforts centered on new feature development.
