Developed a midnight-aligned date and time normalization utility for the octoenergy/xocto repository, focusing on improving consistency in time-sensitive calculations and downstream scheduling. The solution, implemented in Python, introduced a function that normalizes various date and datetime inputs—including naive, timezone-aware, and plain date objects—to a localtime midnight-aligned, timezone-aware format, with None inputs handled gracefully. This enhancement reduced off-by-minute edge cases in reporting and scheduling workflows. The project version was updated to 9.0.3 to reflect the new capability and maintain backward compatibility. Work emphasized backend development, software versioning, and robust unit testing to ensure code quality.
