Nope, I just keep track of the number of seconds that pass by. Because
the OT2m gets busy occasionally, the timing does slip a little bit.
It's not a Swiss watch by any means.

Now, the astute among you will realize that the counters need to be
zeroed at 00:00:00 Sunday morning to be on time. There's no way of
currently pulling time out of a GPS string, or even sniffing one out
of a timestamped APRS packet, so it requires a manual reset at
midnight.

However, one could write a script that would preset the counters to a
specific time and day, and then call that script at that time. As the
timing slips further out of sync, one could call the synchronising
script as need be.

For a script that simply dumps a string into the network every 10
minutes or so, it doesn't really matter if the clock slips slightly.
