Added handling with pop_plus_steps/pop_minus_steps:
'+' usually takes more than one time step.
'-' is usually 1.
Changed behaviour when current time is not found in the list of time steps:
Search for the entry with the smallest distance to 'current time'.
If the distance is smaller than 3 minutes, then use 'current time' as new
entry in the list of time steps.
The file is empty.
