vl-file-systime

What causes "vl-file-systime" to return nil for for an open drawing? What other method can I use to retrieve the date of the currently open drawing?

Thanks

 

To get the "last saved" date of the current drawing, (getvar "tdupdate")
gives a Julian date, to convert to calender date, pass it to this little
function, like this: (ser2cal (getvar "tdupdate"))

(defun ser2cal (serdate)
(menucmd
(strcat "M=$(edtime,"
(rtos (+ serdate 0) 2 8);2415019 add to serdate for MS dates
",DDD\",\" DD MON YYYY hh:mm)"))
)

will return: "Tue, 02 Mar 2004 17:05"

What other method can I use to retrieve the date of the currently open
drawing?

 

Jeff,

Thank you very much, that does the trick!
