The date variables used in the NRD and NRDP instructions are structure variables. The following table lists the internal structures.

When NRD and NRDP instructions receive power, the current time is stored in D1. You can extract the year/month/date of the date variable by specifying a particular date element. When the current date 2005/10/20 is stored in D1, 05, 10, and 20 are stored in .YR, .MO, and .DAY, respectively.
