Good idea.  But I doubt that any TNC keeps that good
of time nor do the sysops keep the clocks set.  Maybe
someone can study this  and report b ack!

Should be simple to do.  Just time the arrival of packets
from two local digis for a few hours and see how much
drift there is in the timing?

Or easier, do a HISTORY from FINDU.  (or maybe FINDU
does not log non-moving posits?)


  May I
suggest that you add to those start times a single digit as follows: 
at the decimal equivalent of the ASCII representation of the last
character of your callsign, and add the last digit to the above
start times.
  For example, My call is N8BJX, 'X' in ASCII is decimal 130, so I
add zero to the above example, and transmit on the 0,10,20,30,40
marks.  Bob, WB4APR would look up 'R' in ASCII as 122, so he would use
  Let's not stress the network by scheduling as many collisions as
possible on every 10-minute mark!
