SQL Query to only exclude data of last 24 hours?

Question

I have the following data:

Table Name: NODE
NID | Name | Date
001 | One  | 1252587739

Date is a unix timestamp. I need a query, whereby I can select only the nodes who's "Date" is older than 24 hours. Something like this:

SELECT * FROM NODE WHERE Date < NOW() - SOMETHING

1. Anybody know how to do this?
2. Does the NOW() - SOMETHING part take into account that the date is stored as a unix timestamp?

Answer 1

Unix timestamp is in seconds. This works with MySQL:

SELECT * FROM NODE WHERE Date < (UNIX_TIMESTAMP(NOW()) - 24*60*60)
