I am looking for a way to "sync" up running a command on 10 boxes at the
So I thought - hey in my program "I can send a command out that I want
to run - this command is also another program of mine, get the current
time, add 5 seconds to it, send this time HH:MM:SS
to all 10 boxes and "schedule" an "at" command to run at that time.
So all 10 boxes are running NTP and I thought it would be fine then if
one box got it slightly faster
than the last it would not matter as the "at" command would schedule the
command to run
all at the same time.
So what mechanizim exists to run command down to the second?
I'd rather not wait an entire 59 seconds to run the command.
