Hi Thomas!

I think your using a different toolset, think that its a c51 toolset.

Think this will work:

unsigned int time = -5000;
        // Set timer 0 til mode 0
	TMOD = (TMOD & 0xf0) | 0x01; // Timer mode
	TL0 = time % 256; // Reset timer
	TH0 = time / 256; // Reload timer
	TR0 = 1; // Timer run

cheers
