Javadoc
This debug/profiling function will print the current time
(in milliseconds) to the log. If the boolean is true, the
garbage collector will be called in an attempt to minimize
timing errors. You should try and minimize applications
being run in the background when using this function.
Note that MS Windows only has 10 milisecond resolution.
The function should be optimized completely out of the code
when the first if-statement below reads "if (false)...", so
performance shouldn't be impacted if you leave calls to this
function in the code (I think).
