MYSQL query / dates older than 1 week ago (all datetimes in UTC)

Question

How do I query a mysql db to return all records with a datetime older than 1 week ago. Note that the datetime table stores everything in UTC, and I should be comparing it in

Answer 1

SELECT * FROM tbl WHERE datetime < NOW() - INTERVAL 1 WEEK

If your table stores datetimes in different timezone than what NOW() returns, you can use UTC_TIMESTAMP() instead to get the timestamp in UTC.
