This attribute is stored with the active calibration set. If a different calibration set is restored, this
attribute reflects the date stored with that set.
smua.cal.adjustdate must be set to the date the adjustment was done using the UTC time and
date. The date is stored as the number of seconds since UTC, 12:00 am Jan 1, 1970.
Due to the internal storage format, smua.cal.adjustdate is only accurate to within a few minutes
of the value set.
Example
smua.cal.adjustdate = os.time()
Sets the adjustment date to the current time set on
the instrument.

Details
This attribute stores the calibration date that is associated with the active calibration set. The
calibration date can be read at any time but can only be assigned a new value when calibration has
been enabled with the smua.cal.unlock() function. It is typically set to the date when the
instrument was calibrated.
This attribute is stored with the active calibration set. If a different calibration set is restored, this
attribute will reflect the date stored with that set.
smua.cal.date must be set to the date the calibration was done using the UTC time and date. The
date is stored as the number of seconds since UTC 12:00 am Jan 1, 1970.
Due to the internal storage format, smua.cal.date is accurate to within a few minutes of the
value set.
Example
smua.cal.date = os.time()
Sets calibration date to the present time set on the instrument.
