Hi,
convert your date to UNIX_TIMESTAMP, which is number of seconds since
1.1.1970, and you can use simple math, as in
$query=mysql_query("
SELECT dtg
FROM techs
WHERE
tech='$user'
AND
UNIX_TIMESTAMP(dtg) > UNIX_TIMESTAMP(NOW()) - 86400
AND
HOUR(dtg)>=7
");
... where 86400 = 24 hours (in seconds)
See <http://www.mysql.com/doc/en/Date_and_time_functions.html#IDX1302>
