I don't understand what the problem is. The program prints UTC, not local
time.

Ok, but then how do I get to print local time?

I think there is a problem here too. On my system, getUTCTime() returns the
local time and NOT the UTC.

Here is my test code...

//-------------------------
import std.date;
void main()
{
    d_time lLocalTime;
    d_time lUTC;

    lUTC = getUTCtime();
    lLocalTime = UTCtoLocalTime(lUTC);

 printf("UTC   %.*s\n", toString( lUTC ) );
 printf("Local %.*s\n", toString( lLocalTime ) );
 printf(">UTC  %.*s\n", toString( LocalTimetoUTC(lLocalTime) ));
}
//------------------------

and here are the results...

c:\temp>date /t & time /t
Tue 18/05/2004
11:18a

c:\temp>datetime
UTC   Tue May 18 11:18:40 GMT+1000 2004
Local Tue May 18 21:18:40 GMT+1000 2004

UTC  Tue May 18 11:18:40 GMT+1000 2004


I expected that the UTC would read as "Tue May 18 01:18:40 GMT+0000 2004"
which is 10 hours behind local time. Instead the getUTCTime() function
returns what looks exactly like the local time!

The conversion routines, UTCtoLocalTime() and LocalTimetoUTC() seem to work
okay.

Maybe getUTCTime() should be renamed as getLocalTime() and then define

d_time getUTCTime()

   return getLocalTime() - getLocalTZA();

This function gets/prints a local time for me. i.e.

import std.date;

int main () {
	d_time t;
	
	t = getUTCtime();
	printf("%.*s\n",toString(t));
	t = UTCtoLocalTime(t);
	printf("%.*s\n",toString(t));
	t = LocalTimetoUTC(t);
	printf("%.*s\n",toString(t));
	return 0;
}

Outputs:

Tue May 18 13:32:05 GMT+1200 2004
Wed May 19 01:32:05 GMT+1200 2004
Tue May 18 13:32:05 GMT+1200 2004

The first and last times are correct 'localtime's whereas they are 
supposed to be UTC times, it gets the timezone correct, and adds it for 
the 'localtime' call but is adding it to an already localtime value so it 
gets a time 12 hours into the future.

I'm in New Zealand. :)

Have you tried DIDE, it has some phobos docs in it. I found the functions 
using that.
