Okay, so I have just fired up the first single mission and here is the file that shows me that:
[21.02.2014 21:39:50] Mission: single/gb/1940_Spitfire_Scramble/scramble_01.mis is Playing
12:00:00 Mission BEGIN
12:00:03 Mission END
Here is the last part of the initlog file that covers that exact time window:
