Errh, no. It is designed for exactly those machines, so that they are |
8 |
independant of their hardware (Mickey Mouse) clock and of course to keep them |
9 |
all in sync with each other (and the Unix servers they connect to). |

That does exactly what NTP tries to avoid: Time jumps. |

So when you're not connected to the net permanently, one has two choices: |
19 |
|
20 |
1) Choose one of your machines as the ntp time server which delivers the time |
21 |
of its internal clock and synchronize each others time with this one. In the |
22 |
end it only matters that the time is correct in _your_ own network, isn't it. |
23 |
|
24 |
2) If even the most accurate internal clock on your network is not accurate |
25 |
enough, plug an accurate time source into one machine you choose as time |
26 |
server, then goto 1). |
