Steps to reproduce:

• Create a new user.
• Set a journey starting on June, 1st, of 8 hours.
• Logout, login as the new user.
• Go to June, 1st and create a new "Full day task".
• Expected: Created a new task starting at 0:00 and ending at 8:00.
• Actual result: New task starts and ends at 0:00.

If you take a look at the generated code, you will see:

var currentJourney = '0';

It looks like the backend operation to calculate the user journey on that date is failing.
