2079, MM can be the month 1 through 12, and DD can be the day 1

:ERRor? SYSTem:ERR? queries the system’s error queue. The response format is:
< error number> ,"< error description string> ".
Comments • As system errors are detected, they are placed in the System Instrument
error queue. The error queue is first in, first out. This means that if
several error messages are waiting in the queue, each SYST:ERR? query
will return the oldest error message, and that message will be deleted
from the queue.
• If the error queue fills to 30 entries, the last error in the queue is replaced
with error -350,"Too may errors". No further errors are accepted by the
queue until space becomes available using SYST:ERR?, or the queue is
cleared using *CLS.
• The SYST:ERR? command can be used to determine if any
configuration errors occurred during the power-on sequence.
• When SYST:ERR? is sent while the error queue is empty, the System
Instrument responds with + 0,"No error".
