Translation of oscilloscope in German

In the that time of the year, when I used to go to school, I had to get up very early and leave the house at around seven o'clock in the morning. At this time it was still night, dark and cold outside.
Sunday is fine. Please let us talk tomorrow to arrange a schedule of that day. I will call you tomorrow, but in any case, here is my number again. We could do it also on Monday next week, if it fits everybody.
After a long sleep we ordered a cab which took us from the hotel to the airport. We were a little sad to leave. The flight over the South China Sea lasted two hours. We landed in Hong Kong's new airport.
