The Sysplex Timer synchronizes each system's time-of-day clock with the other
system's clocks in multiple system installations. Each zSeries 800 system comes
with two integrated timer cards, which allow connection of two Sysplex Timers for
continuous availability. The cable connection at the zSeries 800 is ESCON Duplex,
and matches the cable connection at the Sysplex Timer.
