Programming :: Match Datetime By The Minute (not An Exact Match By The Second)

I have the following query:

Code:
$sql="SELECT table1.datetime, table1.user_id, table2.ip, FROM table1,table2 WHERE id='$id' AND (table1.id = table2.id AND table1.datetime = table2.datetime)";

In table2 the datetime fields are about 1 to 2 seconds off due to the source of the data, which I cannot change.

Is it possible via a query match table1.datetime & table2.datetime by HH:MM (ie. to the minute instead of to the second)?
