Hi All,

  Request your help on below program on how to format or cast 
SysTime to DateTime

import std.algorithm: filter, map, sort;
import std.container.array;
import std.file: SpanMode, dirEntries, isDir ;
import std.stdio: writeln,writefln;
import std.typecons: Tuple, tuple;
import std.datetime.systime: SysTime;
void main () {
auto FFs =  ["C:\\Temp\\BACKUP", "C:\\Temp\\\EXPORT"];
Array!(Tuple!(string, SysTime)) Sorted;
foreach(d; FFs[]) {
auto dFiles = Array!(Tuple!(string, SysTime))(dirEntries(d, 
SpanMode.shallow).filter!(a => a.isDir).map!(a => tuple(a.name, 
a.timeCreated)));
foreach(i; dFiles[]){ Sorted ~= i; }
writefln("%(%-(%-63s %s %)\n%)", Sorted[].sort!((a,b) => a[1] < 
b[1]));
}
}

Output:
C:\Temp\BACKUP\DND3
