App has a problem since we change the time

Few months ago, the app works good but since 2 or 3 months, the date has a problem. When you add a coffee for today, it will save it at yesterday.
I sended an email 2 month ago, they said that they will fix it in the future at the next update but they didnt fix it since now.
Bad for people who buyed a jawbone for Christmas...
