It Worked on Every Environment Except Prod: Getting Daily Reports Right Across Timezones

A daily sales report was consistently showing incorrect data due to timezone discrepancies, with sales from a store in Lagos and another in London both reporting zero sales during their overlap hours. The issue was traced to the use of UTC timestamps, which, while unambiguous in development and test environments, didn't account for local times in production. By adjusting the conversion pattern to account for local timezones, the report now accurately reflects sales across different locations, highlighting the importance of timezone management in global applications.
