^date::now(shift in days)
Constructor creates object of class date, containing value of the current date accurate to a second, using server's system time. If shift in days is specified, the shift will be added, the shift may not be an integer.
The constructor uses local time of the server where Parser works. To find the time in another time zone, use ^date.roll[TZ;…].
As a result, the code will create an object of class date containing current date's value and output the number of current month.
