3.5 PTIME SUBSYSTEM
The PTIME subsystem regroups all the commands related to the management of the
time.The list of the commands supported is the following:
PTIM:DATE?

PTIM:TIME:STR?
PTIM:TINT?
PTIM:OUT <ON | OFF>
PTIM:LEAP?
PTIM:LEAP:PEND?
PTIM:LEAP:ACC?

PTIM?
3.5.1 PTIM:DATE?
This query returns the current calendar date. The local calendar date is referenced to
UTC time. The year, month, and day are returned.
3.5.2 PTIM:TIME?
This query returns the current 24-hour time. The local time is referenced to UTC time.
The hour, minute, and second is returned.
3.5.3 PTIM:TIME:STR?
This query returns the current 24-hour time suitable for display (for example, 13:24:56).
3.5.4 PTIM:TINT?
This query is equivalent to the command SYNC:TINT.
3.5.5 PTIM:OUT <ON | OFF>
Firmware revision 0.57 and later adds support for auto-initialization of time and date
between GNSSDO 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 informa-
tion to the slave unit. The slave unit’s 1PPS reference input can also be driven by the
master unit’s 1PPS output signal, by setting 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 operating in GPS
denied environments.
The following command returns the PTIME output setting stored in NV memory:
