Re: [OT] timers

[Robert McIntosh]

I started out using that approach, and then wrote a simple class that 
does that via a start() and stop() method, then formats the results for 
logging and other purposes. So the output looks like "1s: 345ms". There 
are a couple of other formats for just milliseconds, just seconds, etc. 
Makes it easy to read :-)

Howdy,
I tend to use the simplest of all:
long opStart = System.currentTimeMillis();
... do stuff ...
long opEnd = System.currentTimeMillis();
... elapsed time in milliseconds = opEnd - opStart
I know this approach isn't 100% accurate due to threading issues, CPU
cycles, etc, but it's good enough for every application I've ever
written/used.  It's also consistent, simple to use, and incurs no
overhead.
You will undoubtedly find many timing utilities if you try a google
search.  I haven't found one that claims to always be 100% accurate in
the face of threading issues, so why bother using anything but the
simplest? ;)

Subject: [OT] timers
Does anyone know of a good timer utility, maybe there is one hidden in
commons somewhere? I don't mean a timer like the java.util.Timer and
   

the
 

javax.swing.Timers which are schedule types, but a timer for well,
timing operations. I have a simple one I wrote that works, but I didn't
know if there were any others that might be better.
