NTP works very well, the best timesource ever, and it's in under my control ;-)

I use it for all my PC, router, cams, ... specially for a meteor detection camera. Offset is only a ms max.

hi Thomas,

thanks for your reply. a question, how did you measure the offset less than 1 ms ?

i don't say NTP works bad. it's the opposite, it is great. and i am happy to have it.
what i tried to ask is the fact, if somebody else had the same experience as me, that this NTP has a little offset against others stratum 1 time servers. actually it's not be worth to speak about it. but i did. ( some things i want to know exactly - sorry )

as i wrote in my first posting i configured two additional stratum 1 server as reference.
now i wrote a small shell/awk/gnuplot script for visualization of these endless NTP log files.
attached you can find 2 jpg's
it shows the offset to a stratum 1 in Vienna and the other is in Braunschweig.
it's calculated with the yesterday's statistic files.
my first guess with 6 ms was not so bad. ( in my case )


kind regards
hans
