How should dates be handled and parsed in the LDS?

• A. Keep Dates In Original Format Without Changes
• B. Convert All Dates To Numeric Timestamps
• C. Treat Dates As Categorical Values For Comparison
• D. Normalize Date Formats, Extract Components, And Ensure Consistent Time References

Answer: (D)

Dates come from many sources in different formats, so you need a consistent, unambiguous way to handle them. The best approach is to normalize formats into a standard representation, extract useful components (year, month, day, and possibly hour/minute/second), and ensure a consistent time reference (such as UTC). This makes sorting, filtering, grouping by time periods, and calculating differences reliable across the dataset. If all dates are in a uniform internal format, you avoid misinterpretations caused by ambiguous day/month orders or time zones, and you can perform time-based analyses smoothly. Keeping dates in their original format can lead to confusion and parsing errors. Converting all dates to numeric timestamps alone isn't always sufficient or portable if time zones and human-readable components are needed. Treating dates as categorical values prevents accurate chronological ordering and weakens your ability to perform time-based calculations.
