Hello,
Yes the Tymserve and other similar DATUM / Symmetricom products which
use the Trimble ACE board will fail again in 2016. This is due to the
way the GPS epoch is calculated inside the 2100 : the DATUM engineers
estimated the future leap second insertions to determine GPS epochs,
which was not a so good idea... Our N024 GPS board inserted insteas of
the ACE board corrects this bug, as well as offering high GPS
sensitivity and fast startup. We offer warranty for the next 20 years.
Regards
Olivier
