I’m working on setting the Tiles for the windows phone 8 apps, would somebody tell me how to update the tile time for every minute like the first time tile in the picture below,

I’ve done using ScheduledAgent but that works fine when I start the service in debug mode. . .
I’ve seen an example in here but that one is for metro app. . .
somebody please tell me how to achieve this in windows phone 8. . .
You can’t update the livetile more than every 30 minutes on Windows Phone unless you push out a push notification from a server every minute which wouldn’t be very efficient anyway.
