This command adds support for auto-initialization of time and date between two Jackson Labs Tech-
nologies, Inc. GPSDO units. This allows connecting two units together through the serial port with a
null-modem cable, and having the master unit send time and date information to the slave unit. The
slave unit’s 1PPS reference input can also be driven by the master unit’s 1PPS output signal, by set-
ting the slave unit to external 1PPS sync mode using the SYNC:SOUR:MODE EXT command. This
allows time-synchronization at the nanosecond level between two units which can be useful when
