import std.date;
char[] answer = "Current time is: " ~
                  std.date.toTimeString(std.date.getUTCtime());

Use the Date struct if you want more control over the format.

In D you won't be using zero-terminated strings except for interfacing 
with C functions.  If you dereference a char pointer (like 
*str_time_ptr), you get a char. Just like a you would in C.  If you call 
a C function that returns a pointer to a zero-terminated string, you can 
convert it into a D string like this:

char[] str_timeto = std.string.toString(str_time_ptr);

and the other way around:

char* str_timeto_ptr = std.string.toStringz(str_time);
