calories glance displays wrong time

I have this issue for some time now. In the morning i checked my glance it was displayed as normal the hour was normal and the ammount burned etc... 
But now its 9:20am and my glance says its 6:31 I don't get why because I went back in time on my glance now its says I was burning high ammount of calories in my sleep cus that says I was still sleeping. As the day goes on everything goes back to normal but its annoying. anyone that has the same bug as me? Or how do I fix this
