timeval: Increase accuracy of cached time 4X, from 100 ms to 25 ms.

With CFM and other tunnel monitoring protocols, having a fairly precise
time is good.  My measurements don't show this change increasing CPU use.
(In fact it appears to repeatably reduce CPU use slightly, from about
22% to about 20% with 1000 CFM instances, although it's not obvious why.)

Bug #15171.
