sorting issue

[dwild0]

Sorting them by timestamps might cause ambiguity, because several specific timestamps appear more than once, while not every signal contains every kind of timestamps. More precisely, there is no timestamp, that occurs in every signal. Therefore sorting them by more sorting criteria could also become kind of difficult.

Currently working on following functions:
Func1 : find minimum timestamp that ist not NaT
Func2: sort dataframe by all three columns

Fix that nonexisting timestamps are filled with NaT while converting string to datetime objects. They should be filled with time 0 values with date from existing timestamp. If that is not possible with built in to_datetime function, then a custom converting function has to be made, that converts while taking date from existing timestamps.
