[Q] time label wrong in Lollipop Google Calendar day view topic

In my lollipop phone, (Alliance ROM on Galaxy s5) the day view of the Google calendar app shows the wrong time... all the times are half an hour too early. Example: the label next to the line which is 10:00am shows 09:30,
the 11:00 line shows 10:30.
Which is a bit confusing.
