[PATCH 0/4] NTP support (master)

Hello Gabriel,

I reviewed the patch set and the kern_ntptime.c. Changes in FreeBSD in 
kern_ntptime.c are infrequently. The module is pretty self contained. I 
suggest to import this file into the RTEMS sources due to the coupling 
with kern_tc.c which is already present in RTEMS.

The ntp_update_second() is called by _Timecounter_Windup() under 
protection of the _Timecounter_Lock. I don't think we need the extra 
ntp_lock.

I will work on a patch which includes the current kern_ntptime.c to 
RTEMS. It should be ready by end of next week.

Do you have plans to enable the PPS_SYNC option?
