How to obtain in-game time?

[Smokeynz]

If you can figure out how to call the console( As per in game pilot manual Shift-tab enter tod) and enter "tod" you can gather the "time of day" which is the mission time at that point from mission start.
It is currently hard coded, that is, cannot be altered as per IL2-46(although this was un alterable between patches even for 46)

If a server owner starts his mission via script (TAB-4) or a Server Commander, the script or the commander will 'know' which file the server owner started I guess.
