Does anyone here know of consumer GPS receivers (as opposed to ones
intended for precise time synchronisation) that provide for display or
readout of both the current and future leap second offset data from the
GPS signals? When I asked about this on the tz list a while back Meinberg
receivers and others designed for time synchronisation were mentioned, but
not any of the consumer GPS receivers. (Ideally I'd want both display and
readout of UTC, including 23:59:60; TAI; and the past and future leap
second offsets and effectivity times. The customer enquiries email
addresses and web forms of companies making consumer GPS receivers don't
seem to respond to enquiries that carefully reference the parameters from
the GPS Standard Positioning Service Signal Specification that are of
interest.)
