agement page. The year value only needs to be manually entered once, as it will automatically
increment to the next year each New Year's day. See "Editing the System Time" on page 169 for

NOTE – By default, the "year" fields in the IRIG message are ignored and a user-
defined value is used. Make sure the year is set correctly when the SecureSync is
installed. If the year is not set correctly before NTP achieves time synchronization, it
will use the value entered. The unit will also default to the year entered if it is
powered down during the rollover of the year. If the SecureSync was not switched on
during the rollover, this value must be updated.
NOTE – When the IRIG Input year is updated,

SecureSync starts numbering I/O ports with 0 (only 1PPS and 10 MHz out-
