Mod which manipulate the internal timestamp?

[LegoProfessor]

Hi Freaks

My C:S reach DoomsDay i.e 31.Dec.9999
Reaching this date, the vehicels&Co are only moving one step ahead and one step back. And this endless

And yes there is a mod to change the date, but unfortunately only on the surface.
The internal Int64 timestamo still overflows:

Simulation error: Argument is out of range.
  at System.DateTime..ctor (Boolean check, TimeSpan value) [0x00000] in <filename unknown>:0 
  at System.DateTime.op_Addition (DateTime d, TimeSpan t) [0x00000] in <filename unknown>:0 
  at SimulationManager.SimulationStep () [0x00000] in <filename unknown>:0 
  at SimulationManager.SimulationThread () [0x00000] in <filename unknown>:0

Is there any mod to change this timestamp too?
Or any other clue/hint/idea to solve this issue
