:CORR:DATE DCR ---- Query the time of the last DCR correction operation
:CORR:DATE DCROPEN ---- Query the time of DCR open correction operation
:CORR:DATE DCRSHORT ---- Query the time of the DCR short correction operation
:CORR:DATE1 LAST ---- Query the time of the last point frequency 1 correction operation
:CORR:DATE2 OPEN ---- Query the time of point frequency 2 open correction operation
:CORR:DATE3 SHORT ---- Query the time of point frequency 3 short correction operation
:CORR:DATE10 LOAD ---- Query the time of point frequency 10 load correction operation
Note: The format of the returned data is "yyyy-MM-dd hh:mm:ss", and a return of "----" indicates
that the date is invalid, that is, the correction operation has not been performed.
