Status icons are grey, but should be colored

Symptom:

The vehicles are updating in real time, but the status icons are grey, see "2" above. (Or in earlier versions yellow).

Cause:

The time or time zone on the Windows server is wrong. (in this case it was ~6:03, see "1" above, and it should be ~4:03)

Solution:

Adjust the time in Windows.

This will result in a colored status icon according to "2" below since "1" is corrected to current time and 4:03:05 is less the 10 min from 4:08, see "1".
