/*
		      ShipWars Plugin Sample Source


	To compile this plugin, type:

	cc timming.c -o timming -shared -g

	---

	This example shows how to calculate timming, by sending
	a joke question and then an answer. The interval between
	the joke and the answer is 5 seconds and the interval
	between the answer and the next joke is 10 seconds.


	First, a short lecture about timming. ShipWars uses millisecond
	resolution timming, meaning that timming is accurate up
	to 1/1000th of a second. The member cur_millitime in the
	plugin_data_ref_struct structure (passed on each function
	that is called by the ShipWars Server) contains a pointer
	to the variable that contains the current time of day in
	milliseconds.

	Now the most important fact of the above that will impact
	you is that the value in that variable will `cycle'
	atleast once every 24 hours. So to compensate for that your
	program needs a function that will reset each `time schedual'
	to 0 whenever the cur_millitime is less than the last
	cur_millitime.
