Re: [PLUG] Time & date sync'ing between systems
|
I'm just writing to say thanks to all of you who've contributed to this
thread; I'll be fiddling with the time-sync'ing over the weekend I
guess.
The only thing I found out very quickly is that my local network
machines are not acting as time servers as they are configured, so I'll
go and look at the HOWTO Chris mentioned.
I enjoyed the instant gratification of Leroy's suggestion (rdate
time-b.nist.gov).
