linksys.patch

A NTP client is a program which user can synchronize the time with time server assigned. This prog

Adapted from the version of ntpclient posted by Linksys
at http://www.linksys.com/support/gpl.asp .  They claim to
use their slightly hacked ntpclient_2000_339 in some of
their MIPS/Linux-based wireless routers.  It adds static
linking of resolv.o, changes the default measurement interval
from 10 minutes to 60 minutes, and includes a feeble attempt
to port ntpclient to vxWorks.
