LG Optimus V: How to Set the Clock

I accidentally dropped my LG Optimus V on the floor. The back cover popped and battery fell out. Thank God! It still works after I put everything together. Wait! Not everything. The clock is actaylly exact 1 hour off. It goes back to the normal time instead of the Day Light Saving time.

How is how I get the time correct.

1. Press the power button;
2. Switch on the Airplane mode;
3. Switch off the Airplane mode;
4. Wait

Your phone time will be corrected after the service is reestablished.
