The time since reset is the time since the statistics were reset and the 
sysstats monitoring file updated, which occurs once per hour.  See the 
documentation on monitoring commands. This feature is designed for very 
busy server such as those operated by NIST, USNO, and intended as early 
warning detector of clogging attacks.
