If for some reason data wasnt collected for one or more hour since last pickle,pickles
for the missing hours will be created and filled with data.
If no entries are found for this client in the pickled-times file, we take for granted that
this is a new client. In that case data will be collected from the top of the hour up to the
time of the call.
If new client has been producing data before the day of the first call, user can specify a
different time than system time to specify the first day to pickle. He can then call this
method with the current system time, and data between first day and current time will be
collected so that pickling can continue like the other clients can.
