⎕TS - Time Stamp
⎕TS is an ISO 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 milisecond. 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:

⎕TS is a niladic function, you cannot assign a value to it, meaning NARS2000 cannot set the current date or time through ⎕TS. If you need to set the date or time, you have to use the appropriate feature of your operating system.
