Thanks, Steve.

    import std.stdio;
    import std.datetime;

    void main() {
       auto t = (Clock.currTime() - 
SysTime.fromUnixTime(0)).total!"msecs" / 1000.0;
       writeln(t);
    }

Gives an error: Error: no property 'fromUnixTime' for type 
'SysTime'.

When I do

    auto t = (Clock.currTime() - 
unixTimeToStdTime(0)).total!"msecs" / 1000.0;

I get
Error: incompatible types for ((currTime(opCall())) - 
(unixTimeToStdTime(0))): 'SysTime' and 'long'

and when I do

auto t = (Clock.currTime() - 
SysTime.fromUnixTime(0)).total!"msecs" / 1000.0;

I get:
Error: no property 'fromUnixTime' for type 'SysTime'

I think I am spoiled by 'typeless' scriping languages.
