Not if the delay is always constant.  That you can adjust for.  You
already have to adjust for cable length and such for your GPS, so
adjusting for a fixed delay for a conditional is no big deal.

Of course if you have to check of the DCD changed, that may not be
constant.  A check for whether this device currently has anyone that
wants the timestamp though should be a constant time.
