Solid Time

A dataset of materialized time dimension tables, listing every discrete time value across hours, minutes, seconds and milliseconds, in both time and integer formats. <p><br/></p> It serves as a utility dataset for time series analysis, enabling padding, gap-filling, and reliable joins between tables via the time dimension. While many temporal operations can be performed using built-in date and time functions or complex queries, utilizing this pre-populated table improves query readability, consistency, and performance. <p><br/></p> Maintaining this table as a shared resource reduces data management overhead and promotes consistency across multiple databases and applications.
