So here's the verdict. Using real data from internet won't work. WOFF uses some other info to dictate sun positioning.

Here's Major Test Ickle on 4 January 1917 at 8:00 am. According to the sunrise on that day occurred at 8:50 am.

Here's Major Test Ickle taking off on 2 April 1917 at 6:01 am. Sun should be rising at 6:22 am.

Looks like another method needs to be devised to match WOFF sun status.

The connecting rod out of my brain, my brain,
From out of my arse take the camshaft,
And assemble the engine again."
