[MVMA] Stratum 1 NTP Server

[Jim Bacher, WB8VSU]

Chuck, Most computers have a time of day clock chip that is crystaled controlled. They serve two purposes. One setting date and time on power up. Second it provides an interrupt that keeps the computers time reasonably accurate. The give away is does the computer have a Lithium coin cell? The time chip has a ram area to store computer BIOS settings and needs a coin cell to not lose time and settings. 

Raspberry Pi's don't have the time of day clock. Therefore they can't maintain accurate time. They likely try to get local time off the local network when they power up. My ntp server is set to broadcast time on the local network. 

In /var/log/ntp you should be able to see what the ntp server program did during the internet loss. Sometimes it's is a sub directory, sometimes in the log directory as ntp.log. It of course gets rotated out after awhile to save disk space.
