Hi,

  I tried it but no luck, as the output is a function return in 
type SysTime.

You need to extract the date components and print them separately. There 
is no mechanism to format a SysTime (and it's a hairy subject to be 
sure, every locale is different).

If you want to strip off the fractional seconds, then just zero them out.
e.g.

sysTime.fracSecs = Duration.zero;

The to*String functions of SysTime don't display trailing zeroes and don't
display the decimal point if the fractional seconds are zero.

In general, you probably want to cast the SysTime to a DateTime if you're
going to do something like that. There's a lot of duplicate work being done
if you get each of those properties individually, whereas if you cast to
DateTime, then it does the work once, and the properties for DateTime just
return the correspending member variables. Sometimes, I think that putting
year, month, etc. on SysTime was a mistake, because using thoes properties
almost always the wrong thing to do given how much work is duplicated when
using them, but at the same time, there are cases where the efficiency
doesn't really matter and the simplicity of just grabbing the properties
from SysTime is nice.

yes, I would agree ;-)

Of course the intention was not really to just format it the same 
way as Clock.currTime() does it, but rather to provide a way to 
more easily customise the format, however one likes, whenever one 
likes..

e.g.the following small change to the format string would make it 
return: 20171213_1924_41

(that's more like something I'd use)

   return
             format("%04s%02s%02s_%02s%02s_%02s",
                 (d.year),
                 to!(int)(d.month),
                 (d.day),

                 (d.minute),

Hi All,

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

foreach(d; FFs[]) {
auto dFiles = Array!(Tuple!(string, SysTime))(dirEntries(d, 
SpanMode.shallow).filter!(a => a.isDir).map!(a => tuple(a.name, 
a.timeCreated)));

 Hi All,

Hi All, Thank you very much , was able to resolve the issue by 
changing the writefln line as below.

Sorted[].sort!((a,b) => a[1] > b[1]).each!(e => writefln!"%-63s 
%.20s"(e[0], e[1].to!string));
