Fix toSQLDate Bug

This is probably a bug.

Using date.getUTCxxx produce wrong date-time string because Date() already UTC-ed (I guess).
```javascript
new Date(): Mon Jul 22 2013 10:26:09 GMT+0700 (WIT)
CONVERTED DATE:  2013-07-22 03:26:09
```

```javascript
new Date(): Mon Jul 22 2013 10:25:08 GMT+0700 (WIT)
CONVERTED DATE:  2013-07-22 10:25:08
```
