Answer 1

Here's how I'd do it:

1. Pull the time from the database using the UNIX_TIMESTAMP() function.

2. The UNIX timestamp is in seconds, so add 4*60*60 to it.

3. Convert the modified UNIX timestamp to a date using PHP's localtime() or strftime() function.

   query("SELECT UNIX_TIMESTAMP(someDatetimeColumn) ...");
   . . .
   $dbTimeAdjusted = localtime($row[0] + 4*60*60);
