Calendar's blue today marker points wrongly to the day before

Waking up the iPad from sleep mode or using multitask gesture to run the pausing calendar app in foreground again may show a wrong today pointer in month view.

If the day (i.e. current date) has changed between last calendar usage and actual reactivation its blue today marker points to the date before.

Even pushing the jump today button does not help.

Actualized view is achieved on either a short change to another month and than back (by pushing today button) or on restarting calendar.
