$r = date_parse("8:16:12 01.02.2008");
$d = mktime($r['hour'], $r['minute'], $r['second'], $r['month'], $r['day'], $r['year']);
echo date("H:i:s d.m.Y", $d);

Prints out the following:

8:16:12 01.02.2008

Always remember to set the time zone session setting when using database/sql and timestamps, otherwise timestamps will use the database default:

db, err = sql.Open("postgres", "timezone=UTC")
if err != nil {
    log.Fatal(err)
}
defer db.Close()
var timezone string
err = db.QueryRow("SHOW timezone").Scan(&timezone)
if err != nil {
    log.Fatal(err)
}
log.Println("timezone:", timezone)

Running SET TIME ZONE ‘Africa/Casablanca’; once in a connection won’t work because a pool of connections is used.
