That may actually be the best solution.

I have no control over how fast the remote systems respond with their
data, and under heavy load they will be slower.

Doing it this way, I can tolerate quite slow response ...

The other problem I was mulling over in my mind is that the data
gathering process might (will) be re-started from time to time -- how
would it ever find out the exact tim of the first update so that it
could time its own to be exactly N minutes, to the second, later.

Forcing the first entry on some convenient boundary, then calculating
boundary multiples and using those would fix my problem

Thanks Simon!  I will go play with this...
