+               The delay from the top of the minute before sending
+               the first APRS packet of the minute. Coordinating
+               values for this parameter between multiple devices can
+               allow a single receiver to reliably receive APRS
+               packets from multiple devices. Note that this offset only
+               takes effect while the GPS signal is locked so that the
+               transmitting device knows the current time.
