Dmitry,

I'm not comfortable yet with the timestamp modification patch.  Can you explain 
what exactly you're seeing that makes you want to change this?

How much off is the timestamp?  Just a couple of seconds I would guess?

Looking at this code:

     // Calculate the next time to sleep to that is an integer multiple of
     // the interval time.  Make sure that at least half of the interval
     // passes before waking up.
     now        = time(0);
     sleep_till = (now/interval)*interval;
     while (sleep_till < now + interval*0.5) {
       sleep_till += interval;
     }

#ifdef WATCH_WEB
     measure_web(sleep_till);
#else
     sleep_till_and_count_new_processes(sleep_till);
#endif

and down further in sleep_till_and_count_new_processes() and measure_web(), the 
code is designed to sleep to the next integer multiple of the interval.  So this 
should work fine.

Are you using WATCH_HTTPD or WATCH_WEB?

So something is happening that the process isn't waking up at the right time. 
Are you on a slow system?

Best,
Blair
