⎕TS - Time Stamp

⎕TS is an ISO/IEC 13751 standard niladic system function which returns the current date and time in a 7-element array of year, month, day, hour, minute, second and millisecond. If the dialog below was typed into the NARS2000 session manager window on February 21, 2013 at about 10:43 pm local time, we would see something similar to the following: 

      month ← 'Jan' 'Feb' 'Mar' 'Apr' 'May' 'Jun' 'Jul' 'Aug' 'Sep' 'Oct' 'Nov' 'Dec'
