adding 12 hours to mysql current timestamp

Question

I am trying to filter my query data to only return items where "Meeting Start" is greater than CURRENT_TIMESTAMP but not later than 12 hours from the CURRENT_TIMESTAMP.

Can I add 12 hours to the CURRENT_TIMESTAMP inline below in my query?

Current Working Query:

$query ="SELECT * FROM Reservations WHERE [Room_ID] = '$field' AND [Meeting Start] > CURRENT_TIMESTAMP ORDER BY [Meeting Start] asc ";

Updated Try:

$query ="SELECT * FROM Reservations WHERE [Room_ID] = '$field' AND [Meeting Start] > CURRENT_TIMESTAMP AND [Meeting Start] < (CURRENT_TIMESTAMP + 12) ORDER BY [Meeting Start] asc ";

Answer 1

NOW() + INTERVAL 12 HOUR should do the trick. +12 is ambiguous. 12 seconds? minutes? days? years?
