It didn't jog my memory and doesn't seem to be the issue I'm having, but I 
called home and had the YL do a power-cycle on the TNC and the problem went 
away --- my digipeats are now all of the time-stamped packets that are going 
out *now*, instead of the time-stamped packet from 5-10 minutes
ago.  So the problem was at my station and power cycling the TNC did clear it 
up, at least for now. But it took me a long time to notice the issue, and I'd 
like to avoid it in the future.
