This object holds the CSAT unit's internal calendar date in dd/mm/yy format, readable and writable through the DAY? and DAY= device commands. Like the paired time object, an accurate date is necessary so that fault and event logs on the terminal carry a trustworthy timestamp for later analysis. For example, after replacing a unit's battery-backed clock, an admin would set csat5060DeviceDate to the correct current date before returning it to service.
