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).
