Thanks, I have no more rtc requests for a higher setting now in my  
logs.  I use ports/net/nvnet as my net work driver and here is some  
info on what it is doing.

hw.nv_pollinterval: 1000
dev.nv.0.%desc: NVIDIA nForce MCP2 Networking Adapter
dev.nv.0.%driver: nv
dev.nv.0.%location: slot=4 function=0 handle=\_SB_.PCI0.MMAC
dev.nv.0.%pnpinfo: vendor=0x10de device=0x0066 subvendor=0x1695  
subdevice=0x1000 class=0x020000
dev.nv.0.%parent: pci0
dev.nv.0.wake: 0
dev.miibus.0.%parent: nv0
