How do different SQL databases handle time zones?

Different SQL databases have various methods for handling time zones. For example, PostgreSQL has a 'timestamp with time zone' type, while MySQL uses 'datetime' and 'timestamp' types. Would you like to know more about a specific database?

Yes, can you explain how PostgreSQL manages time zones?

PostgreSQL stores timestamps in UTC and converts them to the local time zone when queried. You can set the time zone for a session or use the 'AT TIME ZONE' clause to convert timestamps.

What about MySQL? How does it differ?

MySQL has a 'timestamp' type that automatically converts to UTC when stored, but it doesn't store the time zone information. You need to manage time zones manually or set the server's time zone.

Are there any best practices for handling time zones in SQL?

Yes, it's best to store all timestamps in UTC and convert them to the user's local time zone when displaying. This avoids confusion and ensures consistency.
