SQL is the first programming language with temporal data types. The SQL-92 standard added temporal data to the language, acknowledging most of what was already in most SQL products by that time. The problem is that each vendor made a trade-off internally.

In this whitepaper, learn about temporal data and how to improve your SQL code. The whitepaper describes how to make time using temporal data, the ISO temporal model, SQL temporal data types, tips for handling dates and times, date and time format standards, time in a database, time zones, interval data types, queries with date arithmetic, and much more.
