In the last days I've been playing a little with the Service Browser and it ocured to me that in some cases i would like to see some other times from my services.
since the profiling object its build from the global variable profiling any method could add some custom variable.
$time = microtime(true);
$result = mysql_query($query);
$profiling['databaseTime'] += microtime(true) - $time;
and in the Browser with some basic reflection one can obtain the variable databaseTime in the profiling Object and build a Label "Database : XX ms" to be shown in the time Statistics. it can be a subitem from the service call time.
Hope this makes it into the next release since I think it needs minimal coding and for some cases it would be usefull to see wich object in particular creates a bottleneck or something like that.
