What is time zone handling in data?

< 1 min read

Time zone handling means adjusting date and time values to a consistent or local time zone.
In my project, orders came from multiple regions with different time zones.
We converted all timestamps to the company’s standard time zone, IST.
This ensured events like order creation or delivery were comparable across regions.
Power Query or DAX functions were used to add/subtract time offsets.
We also stored original time zone for audit or reference purposes.
Without handling, aggregations by hour/day would be incorrect.
It prevents misleading trends or misaligned KPIs in dashboards.
Time zone handling is essential for accurate temporal analysis.
So it ensures consistency and reliability of date-time data across sources.
