DWfile.getModificationDate()

Availability	2.0
Description	Gets the time when the file was last modified.
Arguments	`fileURL`
	The argument is the file for which you are checking the last-modified time, expressed as a file:// URL.
Returns	A string containing a hexidecimal number that represents the number of time units that have elapsed since some base time. The exact meaning of time units and base time is platform dependent; in Windows, for example, a time unit is 100ns, and the base time is January 1st, 1600.
Example	It's most useful to call the function twice and compare the return values because the value returned by this function is platform-dependent and is not a recognizable date and time. For example, the following code gets the modification dates of file1.txt and file2.txt and displays an alert box indicating which file is newer.

var file1 = "file:///c|/temp/file1.txt";
var file2 = "file:///c|/temp/file2.txt";
var time1 = DWfile.getModificationDate(file1);
var time2 = DWfile.getModificationDate(file2);
if (time1 == time2){
  alert("file1 and file2 were saved at the same time");
}else if (time1 < time2){
  alert("file1 older that file2");
}else{
  alert("file1 is newer than file2");
}
